Need help in deciding which destination to go to? Would like to hear from someone who has been to both places. It would be for mother and 11 year old. We are going for 1 week in early December. Looking to find some beautiful beaches and do some snorkeling. Which has the better weather for being warmer? I have been to all the other islands and these are the last two I would like to check out. Which might be more interesting for an 11 year old? Any suggestions.
