Here would be MY plan
1. Secure Lodging for the 7 days and beyond if Nec. , Research Return flight info/ options when avail.
2. Touch base with Loved Ones making sure they are ok, and let them know You are OK
3. Find a Nice Beach, grab a frosty Tropical Drink, and thank the Good Lord you aren't stuck in an Inside Stateroom on some Nasty infected Cruise Ship!
4. Figure out your plan "B" stuff in case TSHTF
5. If you are indeed stuck there, and not in "lockdown" . Enjoy/ Explore the Island.
6. Support the local Bartenders, Chefs and ,Wiatstaff
When life gives you Lemons...
