At any given time, any of the discounts can be the best rate. When you book ask for them all. If any rate is available at the time you book, the ressie will tell you the rate that you request. And if you watch this board, new promotions and rates will be posted by the good people here. If a lower rate than the rate you booked is published , call Universal back and in my experiance, they will give you the lower rate. Last year, I booked under the Ent. rate, but the Fan club rate was later published at lower rate, I called, and I got an upgrade to a pool view room at lower price, by using the fanclub card. The problem is right now for 2004 stays, the Ent. and Fan club rates have not been published. AP rates are only for January. This is giving some people on this board fits. Rumors abound that Universal will release fan club rates ahead of Entertainment book rates, later this month. In my experiance this does matter, just keep on top of the current promotions.
I hope this helps,
