we are going to wdw june 30 for 6 nights, we have narrowed it down for now to 3 hotels all on-site. But i see so many good reviews of other hotels that are so close as well. What are the chances of us not being let in for parks being to full. I don't want to spend this kind of money & not get to enjoy it. We only get 1 vacation a year do to hubbys work schedule.
