You are so correct on the availibilty on rooms in Key West for Fantasty Fest!!!
Also when the event draws closer the rates go HIGHER, keep in mind that the far majority of places do require a min. night stay.
As for the size of the event ....last year was est. at 35-40k people, this year I believe will be larger!!
I think this way because of the past events we (Key West) have had this year were bigger than they were the year before!! i.e.
Spring Break, Hemmingway Days, Lobster Fest, and the most recent due is Labor Day and Poker run which the corridinators are saying huge #s!
So I will leave everyone with .... The weather here is Great hope that you can make it down!!
