I don't like other people's kids! It's very simple. No weird psychology involved.
Dh and I still vacation at WDW because we enjoy the adult-oriented things like the Food & Wine Festival, the deluxe resorts, etc. One thing we really like is lots of dining options in a close and convenient area. So, we always stay at an Epcot resort and we do much of our dining at the non-
DDP restaurants at the Swan/Dolphin. We also always dine late -- 9 pm or later in the hopes that at least some of the kids are gone.
Analyze away!!!
(And, sometimes we see that the kids are actually falling asleep at the table when it's 10:30 pm, but the parents are still determined to have their meal! My only point was whoever said kids aren't allowed after 8 pm was dead wrong!)
