Thanks for the info!
I've already looked at some nice places on St Martin since I posted, and we can get a really nice place for the same price and we know the island really well. I checked with Delta and it would cost us $38 to switch flights to SXM instead of STT for the same week. I was totally invested in experiencing Tortola/BVI's for the first time, but I may have to put a trip off to the BVI's until things are more certain and absolute. I can't go to my friends and tell them that we, may or may not, have to stay in our house for 4 days and for-go VG and White Bay and Sandy Cay and Little Jost and Sandy Spit and Norman Island.
No decisions tonight, but I will have to make one soon as I owe BVI villas money to reserve our villa.
Thanks again and cheers!
