You can get entertainment rates by purchasing an entertainment book at www.entertainment.com. You can check the room rates before purchasing the book by calling 1-800-BEASTAR and asking them if there are any entertainment rates available for your dates. If there are, then go ahead and book the room then purchase the entertainment book.
You must have a fan club card in order to get fan club rates. Tinkerbarb (see the fan club thread on this board) is really great at getting fan club cards to people. You can check fan club rates by going to www.loewshotels.com or www.universalorlando.com and using promotional code FAN.
