Hey Lily Rose,
I am from the Turks and Caicos (15 years now) and have experienced many hurricanes on the ground as well as seeing everything the media reports. First of all, wait a full 2 weeks before making any decisions. A week max is usually what it takes to get power, communications etc going in the major areas, Resorts will be taking care of their employees and any tourist there with limited resources. The second week is for the resort to assess what damage (if any) has happened and let them regroup. You have a good 7 months for them to get sorted which is plenty of time. With the damage to the agricultural crops, the country will be needing tourism more than ever and unfortunately the sensational media reports will cause many to cancel vacations when their vacations will be fine. Tourism will be a top priority because that brings money in.
One of the main reasons this is so damaging to St lucia and St vincent is first the loss of life and second the destruction of the agriculture (banana and plantain crops which account for up to 40-60% export and GDP). I have yet to see any reports of resorts and destruction or seen footage of those (and I guarantee if it had happened it would be on the media). Everything I am reading on the storm carib site is talking about the water damage (flooding) and road damage to certain areas (these are reports from natives and expats logging on from St Lucia and telling what is going on in their areas, I still don't see anything about resorts.) It's going to be a week or two just to get communications up and assess everything.
3 years ago the Turks and Caicos was hit with a Category 5 hurricane head on. On two of our smaller (not touristy islands) we had many homes and buildings (that were 30-40 years old and not to hurricane standard) destroyed. Provo, the main tourist island, had some trees and power lines down but that was it, as all of our resorts and most homes here are well above standard. The headlines for over a week on all of the newswires and TV reports was that 90% of the Turks and Caicos islands were destroyed. On one of our islands with a poplulation of 400 people, over 90% of the homes were destroyed (there are no resorts there) but on our main island we were all fine. It was a nightmare for hotels because people cancelled based on news reports which were sensationalized to the extreme. Give yourself a few weeks and then call the hotel directly (or your wedding planner etc).
I hope and expect you will get good news!
