The entertainment book really pays for itself, there are a large number of other travel related coupons in the entertaiment book in addition to the hotel discounts. Some of them are detailed here: http://www.travelcouponsonline.com/entertainment.html

& a couple more codes that are non-restricted (anyone can use):

FXL - Marriott.com Florida Promo
THM - Theme Park Package
