Generally, no. The really big theme parks (Universal, Disney, Sea World, etc.) usually only offer a few dollars off in coupons in the Entertainment Books. You can get the same discount from numerous other places -- AAA, fast food restauarant coupons, supermarkets, etc. I have seen some local ediitions have valuable 2-1 coupons for more local "theme park" type attractions -- like Polynesian Village on Oahu, Old Tucson in Arizona, etc. If you want to check whether a specific attraction participates, you can comb each local edition on entertainment.com.
