I am sure Disney expects people to leave property once, or maybe twice during their vacations. There is just way too much to do in the central Florida area. However, what they should be concerned about is people staying over at Universal and not Disney. They should be concerned that HP will be so successful, and so huge, that it pulls people off for 2 or 3 days, just to go to Universal, not including the 1 day for SeaWorld. I can see people choosing between DHS, AK or that extra day seeing Harry Potter. My feeling is, people will choose that extra day to see HP. And if that happens, then people may start thinking, why spead these prices for a Disney resort if we are going to only spend 3 of our 5 days there? Let's stay in I-Drive, spend a lot less for our hotel, spend 3 days at Universal to see HP, then 2 days at Disney.
