Hi: I am travelling with my wife and 2 sons (ages 20 and 18) around the 3rd week in August (7days/6 nights) and we are trying to decide whether St. Maarten/St. Martin or Grand Cayman would provide the best vacation. It would be preferable to stay very near to a nice beach as we spend lot of time in the ocean. We were thinking of going "vacation rental" instead of hotel as it seems that there are much newer properties available in this category (but we cannot seem to find much reviews on these) and we very much prefer to eat at local restaurants rather than in hotels. The other thing that is very important to us is free internet/wifi service as my sons spend a lot of time remaining connected. The attraction that we have for St.Martin is the Dutch/French experience while for Grand Cayman it is the famous 7 mile beach. The problem that we have is that we really do not know much about either place and would really appreciate some advice.
