We are going to be in ambergis caye around new years this year for the first time. we are a family of 5 with 3 grown children. do you have any suggestions on accomodation, preferably with a kitchen and on the beach. we just want something comftorable and clean, not expensive. also, is it necessary to pre-book at this time of year (around december 26-january 2) or can we arrive there and start looking for accomodation. thank you!
