We ALWAYS do character breakfasts. We are going Sept 8-16 (finally dropped under 100 days but the wait is killing me too!!). We love the character breakfast at GF and Crystal Palace since I love Pooh Bear. I am 30 and my husband, who also loves these breakfasts, is 32. We have no kids yet but feel WDW is the only place we can do this and still be considered "normal"
We did have a bad experience though on our first trip to WDW together in 2003. We were eating at Crystal Palace and a very rude family was sitting next to us. Their son, who had been jumping up and down on the booth the whole meal (he was around 5 or 6) leans over and puts his head in my husband's meal (yes this is no joke). The entire back of his head went into my husbands scrambled eggs. I did not expect the kid to apologize but I thought his parents would on his behalf or they would tell their son to apologize. Not a peep out of them! They actually gave us a dirty look when they were cleaning the food out of his hair as if it were our fault eggs got into his hair.
So my husband, out of annoyance, says that he "lost his appetite" and pushes his plate forward. Aka, he is upset and wants to go ride some rides so let's go. Well, the family heard this and had the audacity to say to us, "You do know this is a kids meal. If you have a problem with kids, you should have sat by the window or gone somewhere else". The only thing that came out of my mouth was directed to my husband, but loud enough for them to hear was, "Did she actually say what I think she said". Luckily nothing more was said and in the end the manager comped his meal which we weren't even expecting.
Apparently the lady had not grasped the concept that in such a busy restaurant you cannot choose where to sit. And we paid just as much for that meal as they did and expected to enjoy it.
Moral of the story, you have a right to eat where you want. And even if you are 30 or 80 for that matter and Pooh Bear or some other character at breakfast brightens your day or puts you in that Disney frame of mind, well them go for it and enjoy (no matter what anyone else may say!)
