There are too many to list, and many more are actually on-line than appear in the back of each entertainment book. To find out which hotels are available, go to
www.entertainment.com and click on the small blue link in the top right called "buy a book". Scroll down until you find the "The Orange County Book (2004)" and click on the "view it" link.
You have to scroll down the page to find the TRAVEL section at the left then click on the hotels link. There are two types of discounts, a 50% and a best rate.
It was hard for to me to see at first, but they start you out on the 'best rate' search, but there is a TAB at the top of the box that says "hotels at half price" that you can go to and search on as well.
I had some entertainment bookings at the Fairfield Inn by Marriott ($62) and Holiday Inn Anaheim Resort ($67.48) for the Easter Weekend, to give you an idea of prices available for properties near Disney.
I ended up cancelling them just the other day as the prices on Hotwire were too good to pass up -- but the Entertainment prices were still better than Expedia and Travelocity (and of course no problem to cancel, either).
Cheers.
