My philosophy is that children don't learn how to behave in nice restaurants if they never experience them. We've brought our kids to the fancier restaurants at WDW since they were 5 years old (the age of their first Disney trip). We've always found the servers to be wonderfully accommodating and prepared to help the kids enjoy their dining experience. But most importantly, we've learned to come to any restaurant prepared to keep the kiddos occupied. As some examples, our kids have always been crazy about the card game Uno, so I never travel without it. I always have Uno in my purse. It's saved the day many a time. "Spot it" is another travel friendly game that I sometimes have on me, though they've outgrown it in more recent years. We're also very careful about how much snacking we allow in the parks in the hour or two leading up to our dinner reservations. I want the kids HUNGRY so that butts stay in seats and they're focused on the meal. Now that they're older (5th graders), my husband and I also keep a few books loaded on Kindle apps on our phones so they can read when they're bored. Last trip we let them travel with our old pocket digital cameras so they could take their own pictures of our adventures. They had a BLAST looking over their pictures each day at dinner. Honestly, we had a lot of great conversations over our meal about our favorite moments of the day thanks to their picture taking, so that's a fun tradition we'll encourage for years to come.
