Oh, no doubt, SOME will certainly be turning the convention into a vacation. But certainly not all.
I'm simply giving a reason as to why alot of the rooms are booked up. It's obvious, alot of people are worried that crowds will be absurd the first couple of weeks in February, and it's not gong to be like that.
Sure, might be a little busy on the weekend, but I would bet money, during the week, you won't see more than a 10-15 minute wait for the most popular attractions.
February (the entire month) is ALWAYS a big convention month in Florida. It gives these companies an excuse to get away from the cold weather. It's never affected the first 2 weeks in February to my knowledge.
