We were uncertain whether we would use our timeshare on December 30, 2017 when our resort announced that they would reopen 12/1/17. When they updated their expected opening to 1/1/18, we took that as a sign to postpone our vacation to a later date.
This issue is a personal one. While some have suggested that you could be a burden to the recovery, most know that a country that relies on tourism for survival critically needs your visit.
Another thing to consider is the expectations you have for your vacation. Those that want nightlife, casinos and lots of activities may be disappointed. Sand gravity will still be available and a welcome goal to many.
Many of us are fortunate enough to have friends as residents of SXM. They will likely be the best sources for accurate information.
Ultimately, you must decide what works best for you and then, go with it.
