According to forum posts, travelers can use an Opal card for easy access to multiple modes of public transportation in Sydney, including trains, buses, and ferries. The card is free, and top-ups can be done at newsagents or using machines at stations.

For many users, contactless credit cards offer the same benefits as the Opal card, including fare caps and discounts. This method is especially recommended to avoid leftover funds on an Opal card, as unused balances are not refunded but remain valid for seven years.

Some travelers noted that Sydney's public transport system is extensive, covering major areas and attractions efficiently. Trains from the airport go directly to Central Station and Circular Quay, and buses serve routes across the city. The B-Line bus and regular ferries, like the one to Manly, provide scenic and practical transport options for both daily commutes and tourist explorations.

Travelers have called out the train as a quick and direct option from Sydney International Airport to the city center, emphasizing its convenience over buses, which may involve transfers and longer travel times.

For many users, the Langham and the Pullman Quay Grand are also favorable options, with the former being praised for its less conferencey feel and the latter for its large rooms with balcony suites. The Meriton chain, especially for its penthouse options, is preferred by some for its locations like The Rocks.

Travelers have called out the Australian Museum and the Powerhouse Museum for their interactive exhibits that can be particularly enjoyable and educational for children. These museums offer a mix of history, science, and technology.

From Katoomba, options such as public buses or the hop-on hop-off (HOHO) bus are available to navigate the area, allowing access to major attractions like the Three Sisters and Scenic World.

For those preferring flexibility, self-driving was suggested as a viable option. This allows visitors to explore the Blue Mountains at their own pace and access various hiking trails and viewpoints, although parking can be challenging at popular spots during peak times.

Alternatively, several users mentioned the availability of guided day tours, which often include transportation from Sydney and stops at key attractions. These tours can be convenient for those who prefer structured itineraries and include additional stops like wildlife parks.

Some travelers suggested the Pullman Quay Grand as a top choice for its location and views, though it can be pricey. The Four Seasons is noted for being steps away from Circular Quay, offering convenience although some users found the rooms small. The InterContinental is another recommended option, with slightly better room sizes but a slight uphill walk from the Quay.

For those looking for apartment-style accommodations, Quay West is a popular choice, offering larger spaces and sometimes cheaper rates compared to Quay Grand. Budget-conscious travelers mentioned the YHA for its location and rooftop balcony, providing a more economical stay without sacrificing too much convenience.

Travelers have called out that prices for accommodations can vary greatly based on the time of year and specific events, suggesting flexibility and early booking as key to securing a good deal.

Kiama is known for its picturesque views and less crowded beaches, while the Northern Beaches area is highlighted for its relaxed atmosphere and accessibility via public transport, making it a practical choice for visitors staying in Sydney.
