The best advice about hotels I can give you is to listen to word of mouth from others or search for the hotel review sites and read what others say about them.
We went to Disney World last year and the hotel was not very good at all, beginning with wet carpet, an elevator that did not work half the time, etc. I learned this year to go on what others are saying before I selected a package deal.
Have a great time! It is a wonderful place to visit and your cares just melt away while you are there even though it is a rather hectic vacation.
