The Walt Disney Travel Company, does deals with most hotels in the region. These packages, which they sell directly, but also through AAA, Costco, GetAwayToday and many other folks.
But in reality, more folks prefer to book their Air, Hotel and then tickets separately.
Favorite services due to miles, points, a credit card, etc. work with Air and Hotels, and tickets are the same price.
So shop around, you can usually do better than buying a package.
And some of us are willing to help you here.
Just ask questions, and be prepared to answer things like dates, who is in the group, likes/dislikes, etc.
Have fun planning.
