Thanks everyone, for the encouragement!!
I am not really worried about being at WDW if there is a hurricane, but being able to get there (from home in AL) if there is a lot of damage here!!!

I called Disney last night and they were so accommodating... said if we should have problems arriving on time, they will work with us, not to worry etc. And DH said we are going no matter what, so I feel somewhat less anxious about it this morning!
