I do believe though, that the entertainment rate is the best discount for Hojo's. If you do the AP discount or the DIS discount, it is not as good. I'd say just get an entertainment card and go for that deal. You can't beat it!
Other discounts that can be had, can be found in the cards entertainment book. With the card, you can register it on line, to receive further special deals. The www.entertainmentbook.com site, you can see what kind of offers they have in your area, or any other area that may be of interest to you.
