For families visiting the Yucatan Peninsula, an all-inclusive resort with amenities catering to children of all ages, including teens, is recommended. Some travelers have highlighted the importance of a resort having a good teens club and sports facilities like a basketball court.

According to forum posts, the Secrets Chain, including locations like Maroma, Akumal, and Playa Mujeres, is highly favored for adult-only all-inclusive resorts. These resorts are praised for providing good value for money and offering amenities such as swim-out rooms or private pools, nice beaches, and 24-hour room service.

For the most luxurious resorts in the Yucatan, travelers have named Rosewood Mayakoba, Banyan Tree Mayakoba, Viceroy, Esencia, Belmond Maroma, Chable Maroma, Palmaia, and Grand Velas as top choices. These resorts are known for their high-quality facilities and services.

According to forum posts, the primary bus service in the Yucatan Peninsula is ADO (Autobuses de Oriente). It is noted for being safe, reliable, and reasonably priced. This service connects major cities and towns across the region.

For travel between smaller towns or areas not covered by ADO, travelers have mentioned using second-class services such as Mayab or Oriente. These buses generally operate from the same terminals as ADO but do not offer online schedules. They are described as fairly comfortable despite lacking certain amenities like onboard toilets.

Some travelers recommend using colectivos (shared passenger vans) for reaching destinations that are not on the main ADO bus routes. These are particularly useful for shorter or more local trips within the region.

It's highlighted that Playa del Carmen has two ADO bus terminals, the Turistica and Alterna, with the latter serving longer-distance routes. The frequency of buses, especially between major locations like Cancun and Tulum, means that tickets do not generally need to be purchased in advance, except for airport transfers which are in higher demand.

According to forum posts, the ADO bus service is a popular choice for travel from Cancun to Merida, noted for its comfort, frequency, and reasonable pricing. Buses are available directly from Cancun airport to Merida with several departures throughout the day. The journey typically takes around 4.5 to 5 hours, and the fare is approximately 740 pesos.

Some travelers mentioned the option of driving from Cancun to Merida via the toll road, describing it as an easy and safe route, albeit monotonous and somewhat costly due to toll fees. It was advised to start the trip with adequate fuel since refueling options are limited along the toll road.

For those considering different departure points within Cancun, there is frequent ADO shuttle service from Cancun airport to the central bus terminal in Cancun city, where more bus options to Merida are available, including the luxurious ADO Platino service.

According to forum posts, businesses in the Yucatan Peninsula primarily accept Mexican pesos. Some travelers mentioned that while US dollars are accepted in tourist areas of Quintana Roo, the exchange rates are often unfavorable.

For many users, obtaining pesos either through ATMs in Mexico or exchanging them at home before travel is recommended. This ensures they have the local currency upon arrival, facilitating smoother transactions and possibly better exchange rates than those found at airport exchanges or in tourist spots.

Some travelers have recommended the Excellence Riviera Cancun for its upscale amenities and food options, emphasizing the importance of luxurious pools and service. The Moon Palace is suggested for families needing water slides and various activities, while the Royalton Riviera Cancun is noted for its large waterpark and modern rooms.

For those looking for a calmer beach experience, Hyatt Ziva Cancun and Grand Fiesta Americana Coral Beach are mentioned for their calm waters and proximity to the airport. Travelers seeking adult-only environments favored the Riviera Maya area for less crowded, all-inclusive resorts suitable for relaxation and food quality.

For a less crowded beach experience, properties on specific beaches like Puerto Morelos and Akumal were suggested. The Riu Palace Las Americas was also recommended for its good service and less crowded environment.

According to forum posts, Cancun generally experiences hot and humid weather, with average daytime highs ranging from 29° C to 34° C and overnight lows around 23° C to 25° C. The humidity often makes it feel hotter than the actual temperature.

Some travelers said that while forecasts might indicate rain daily during the wet season, actual rainfall typically consists of overnight showers or brief afternoon rains, and not all-day downpours. However, during hurricane season, particularly from August to November, there's a higher probability of tropical storms which can lead to extended periods of rain.

For many users, November is suggested as a good time to visit Cancun due to lower rainfall and the end of the hurricane season, making it less likely for vacations to be disrupted by weather. Conversely, September is noted for having the highest amount of rainfall and a higher risk of hurricanes.

According to forum posts, the choice between Holbox and Isla Mujeres depends largely on personal preferences regarding the ambiance and activities. Isla Mujeres is often described as busier, with more options for restaurants, hotels, and activities, particularly appealing if traveling with children.

Some travelers said that Holbox offers a quieter, more laid-back atmosphere compared to Isla Mujeres. It is less developed and commercialized, making it appealing for those seeking a more serene escape. However, recent posts have indicated that Holbox is also becoming more discovered, though it still retains a quieter vibe than Isla Mujeres.

Travelers have called out that both locations offer beautiful beaches and opportunities for swimming and snorkeling. The decision may also hinge on the time of year; for instance, seagrass (sargassum) issues can affect beach enjoyment, though it's typically less of a problem in mid-February.

Ultimately, your choice might depend on whether you prioritize a bustling island experience with plentiful amenities (Isla Mujeres) or a more relaxed, nature-focused visit (Holbox).
