We were at Disney during the week that Katrina hit (it actually hit on the day we were leaving) and they had just started the "free dining" packages (if memory serves). I will not kid you, it was hot and I mean darn hot. AT 9 in the morning we would just be getting to the parks and drenched in sweat, the parks were more crowded than usual (however we had Universal to ourselves) and Dining ressie were at a premium but it was the best darn trip ever! Crowds smowds and I took tips from the boards and made plenty of dinner ressies before we went down. We ate like kings and all of us had the time of our lives. Yeah we had some freakish weather but trust me when it is hot outside, you welcome the brief storms, it cools things off. If you go down knowing the worst that it can be and your okay with that, then it makes for a better trip. I am a firm believer in you make things what you want og them, if you follow the advice on the boards and some books, plan accordingly, there is no reason why you can't have a great trip even if it is hot and or crowded and bad weather (besides Orlando is in the center and while they can and have been hit by hurricanes, it is less likely than the coast).
I say go for it, for the prices that they are offering and the money you save on the free dining, you'll be kicking yourself that you didn't go. The best part of us going was the free dining..It gave us an almost all inclusive feel to Disney - the only thing we paid for were our souvineers - it lifted that "oh my gosh are we going to spend a fourtune on eating" feeling I have always had when I visited.
Go...
GO.....
HAVE A BLAST!!!!!
