According to forum posts, Kuala Lumpur offers a variety of public transportation options including trains, monorails, and buses. The train system, consisting of MRT, LRT, and KTM services, connects various parts of the city and is complemented by a monorail service that facilitates travel within the central areas.

Some travelers mentioned the GO-KL City Bus, a free service that operates across multiple routes in central Kuala Lumpur. This service is available to all passengers, both locals and tourists.

For many users, the train is a preferred mode of transport due to its efficiency and coverage of major attractions and districts. The system is straightforward to navigate, with ticket purchases available at machines or through reloadable cards like the Touch N Go.

Travelers have called out that while taxis are available, they are generally not recommended due to issues with fare consistency. Instead, Grab is widely used as a reliable and cost-effective alternative for areas not directly served by public transport.

According to forum posts, JW Marriott and Ritz Carlton are highly recommended for their service and location in Bukit Bintang. Some travelers have expressed satisfaction with JW Marriott's overall hospitality and cleanliness. The Ritz Carlton was noted for its more intimate and quieter setting compared to the busier JW Marriott.

For those seeking modern and luxurious accommodations, the Banyan Tree and Mandarin Oriental are also favored, with the Banyan Tree particularly praised for its rooftop bar offering stunning views of Kuala Lumpur. Additionally, the Intercontinental has been recommended for its proximity to KLCC Suria Mall and the Petronas Towers, along with excellent staff service.

For budget-conscious travelers, forum users have suggested hotels like the Melia, the Suites @ Times Square, Swiss Garden Hotel, and Furama Hotel, which offer reasonable standards of comfort within a moderate price range near major attractions and public transportation.

According to forum posts, popular shopping destinations in Kuala Lumpur for mid-range budgets include Pavilion Mall, Sungei Wang Plaza, and Mid Valley Megamall. These malls are noted for offering a mix of affordable and brand-name stores.

Some travelers mentioned Times Square and Sungei Wang Plaza as favorite spots for cheaper goods and bargains, frequented by both locals and tourists. These malls are known for their vast variety of affordable products.

For those looking for more upscale shopping, the Pavilion Mall and KLCC have been recommended. These locations are known for housing high-end brands and luxury items, providing a more premium shopping experience.

Travelers have called out specific shopping needs like electronics at Plaza Low Yat and kids' items at Mid Valley Megamall. These specialized shopping experiences cater to specific interests and requirements of visitors.

According to forum posts, travelers have access to multiple lounges at Kuala Lumpur International Airport (KLIA). The Plaza Premium Lounge and Sama Sama Express are notable mentions. However, some travelers expressed dissatisfaction with the Plaza Premium Lounge, describing it as noisy, overcrowded, and grubby, despite complimentary access.

For those transiting through KLIA2, there are lounges available, but feedback from users suggests they might not offer good value for money. Descriptions include small rooms and a limited selection of food, making it less appealing for relaxation.

Travelers flying with Emirates or Malaysia Airlines might have access to specific lounges such as the Emirates Lounge, depending on their ticket class. The Golden Lounge is accessible to passengers traveling on Malaysia Airlines, with the possibility of purchasing access if not included with the ticket.

Despite some critiques, there are lounges that provide essential amenities like showers and hot food, as noted in the Plaza Premium Lounge. For those looking for a more comfortable option, the Tune Hotel offers day rooms with included food and drink, which might be an alternative to traditional lounge access.

According to forum posts, KLIA offers a range of public transport options including buses, taxis, and trains. The KLIA Ekspres and KLIA Transit trains connect the airport to KL Sentral, with the Express being a non-stop service taking approximately 25 minutes.

For many users, taxis and private limousines are preferred for direct and comfortable transportation to and from KLIA. Official airport taxis or limos can be booked at the airport via a coupon system, ensuring fixed prices to your destination.

Travelers have noted that there is no airside bus service between KLIA1 and KLIA2. Instead, a landside train service, costing RM2, is commonly used, although there used to be a free bus service pre-pandemic; the current status of which is unclear.

According to forum posts, the fastest way to transfer between KLIA and KLIA2 is by using the KLIA Ekspres or KLIA Transit train. The journey takes about 2-3 minutes and costs RM2 per person. Trains run every 15 minutes during peak times and every 30 minutes off-peak.

Some travelers mentioned a free shuttle service that operates between KLIA and KLIA2. The shuttle runs every 10 minutes and the journey takes approximately 10 minutes. However, details on the current availability of this service might need verification through the official KLIA website.

Travelers have also used taxis or Grab for transfers between the terminals, though these options are generally slower and cost more compared to the train. The choice of mode may depend on personal preferences or specific travel needs like carrying heavy luggage.

According to forum posts, Kuala Lumpur offers numerous money exchange options across various locations. Travelers have highlighted Pavilion Shopping Centre, Bukit Bintang area (including Sungai Wang Plaza and Low Yat), KL Sentral, and Nu Sentral Mall as popular spots. Mid Valley Megamall and Jalan Bukit Bintang are also frequently mentioned for competitive rates.

For many users, the best rates are often found away from the airport and hotel exchanges. It's suggested to check daily as exchange rates fluctuate. Websites like get4x.com and mymoneymaster.com.my are recommended for tracking the best available rates. Additionally, travelers suggest bringing clean, unmarked notes for exchange to avoid rejection.

Some travelers said it's advantageous to carry USD as it's favored by money changers. However, it's generally recommended to exchange directly into Malaysian Ringgit (MYR) to avoid double conversion fees.

For short layovers (around 5 hours), travelers are generally advised to stay at the airport to avoid the risk of missing a connecting flight due to possible delays in transportation or lengthy customs processes.

For those keen on stepping out, Mitsui Outlet Park, accessible via a free shuttle, is a recommended shopping destination close to the airport. Travelers should ensure they return to the airport at least 1.5 hours before their flight.

For layovers extending up to 10 or 12 hours, travelers are suggested to venture into Kuala Lumpur city. Key attractions include the iconic Petronas Twin Towers, shopping at Suria KLCC, or exploring local culture and food in areas like Kampung Baru or Bukit Bintang. The KLIA Express train provides efficient transport to the city center.

For those exploring the city, luggage can be stored at airport storage lockers, allowing for more comfortable travel without the burden of heavy bags.

Travelers should check visa requirements based on their nationality, as some may need to arrange visas beforehand to leave the airport during their layover.
