Planning a trip to St Maarten for next Sep. This will be our first time there and staying in a timeshare on Cupecoy Bay Beach. First question is this, I know Sep can be a gamble but what is the weather really like during this time? Also power requirements, american or european? Most of my other questions have been answered by reading this forum such as driving and safety, but still deciding on either the location of Cupecoy Bay beach or Simpson Bay, both timeshares, any advice?
