I am staying at the Ocean Coral and Turquesa from February 28th through March 7. I (mom)am going with my daughters (ages 14 and 17). This is our first trip to Mexico and anywhere else for that matter. I would appreciate any suggestions! How much cash should I bring? Do I pay for taxi rides with American money or credit cards or Mexican Money? We plan on going to Excaret one day and am wondering how I pay for that! We were suppose to go with friends but with the economy they backed out. What will there be for my daughters to do? Any information would be greatly welcomed.
