I would too- their dining plan option is pretty subpar. I only bother with it in September with the buy one get one 50% off. Otherwise, the $1 or $2 potential savings per plan just isn't worth dealing with 20 cards I have to carry around.
Heck- just in typing that, thats the worst part- the cards. It's unreasonable to expect a family to get the dining plan with that amount of cards.
Seaworlds all day plan is ridiculously awesome- love it. Although I never see value in Disney's dining plans (see: I hate buffets post)- but their deluxe plan- and the trick I use as a DVC member is certainly something I do everytime until the loophole is closed. I'll bet I get $3-4k value in food my trip coming up here in 2 weeks.
I guess what I'm saying is- Universal needs to consolidate their dining plan into an easier to use system that links to a single card. And; subsequently, allowing me to find a way to cheat.
Linking it into your hotel key would be ideal and if they expanded it to CityWalk it would be even better.
I've been tempted to walk in at around 4pm and ask what they do with all the left over food. I imagine it just gets thrown out?
What they could do is keep the buffet going through dinner time but make it an upscale restaurant that's open to the GP.
A few of the buffets in Vegas give you a box that you can make one trip to the buffet, fill it to the top with whatever and it's only like $20.
