We just yesterday returned from AC, and the Playador. It is a good middle of the road property. There is a bit of construction, so that may be a concern. The service is typical Belizian, but very friendly and helpful. The bar there, Crazy Canuck is the best! Don and Carol make the best drinks on the beach, try the Mango Tango! The dive shop there is wonderful, especially for snorkelers, non-divers, or lower level divers. Oliver and his gang are the best. Very easy-going, knowledgable, and so friendly.
As far as the rooms, they are AC'ed, and there is a tv in the sitting room. Great sunrise views, and although it ain't the Hyatt, it was overall a pleasurable trip.
Also, Playador is a great location. Just enough out of San Pedro to be perfect. Grocery store is within walking distance.
Woody's restaurant is across the street and has great food. But absolutely don't miss the town stuff, the croissants at Ruby's, and make sure you plan a visit to hear Barefoot Skinny play (Fido's, Mangos, just ask around). And if you want to keep in touch with home, there are 2 internet coffee shops.
Have fun! We hated having to put our shoes back on!
