Ugh!!! I'm a Tropical Strom Faye survivor too! Went thru 2 ponchos!! I had water park tickets and didn't know if we'd be able to use them. My fingers were so waterlogged I had no finger prints.
But on the bright side. The crowds were less, lines shorter, guess cause the locals stayed away! And the rains eventually did stop, and the last half of our trip we had sunshine and water parks.
Hang in there
