When DH and I were planning where to eat, we tried to look for places that weren't the "traditional" choices (CRT, Le Cellier, etc). We booked several resort restaurants, including Olivia's, Boatwright's and Spoodles.
Not to make excuses, but with in-park dining, you're going to run into people that have been there since the crack of dawn, in the blistering heat, lugging around three cranky children who just want to eat. Putting up with that kind of stuff for 10-12 hours is bound to make anyone not as friendly and chipper as we perhaps think they should be....regardless of whether they're dining for "free" or not.
Personally, I think the offer of
free dining was a great idea. It gives families (including my own) that would not normally have a chance to eat at some of the nicer restaurants a chance to really enjoy their vacation.
It's been so long I don't even remember what the OP said, but for everyone else that is having a cow over the socio-economic situation of Disney travlers, I'm a Medicaid caseworker with our county social services agency...and believe me, I've seen MUCH better behavior out of some my clients than my coworkers. It's all in how you're brought up.
