Making Advance Dining Reservations (ADRs) is always a good idea, regardless of crowds. If you are an advance planner and know when you want to eat, an ADR is good insurance against a very long wait or being told you have to come back in 2 hours. It also doesn't cost anything, so it's worth it just in case, know what I mean?
Also, I hate to break this to you, but it will be a little more crowded than you think. There's something called Jersey Week every year. Each year, all the NJ schools close due to a statewide teachers conference on an early-November Thursday and Friday. This year, it's Nov. 8 and 9. The 8th through the 10th will be pretty crowded ... not Christmas crowded, not Easter crowded, but more like summer crowded. My reservations begin on Sat. Nov. 3. Many people, like us, take the kids out of school on the Monday through Wednesday of that week and make an entire week at WDW out of it. Many teachers skip the conference and go down to WDW themselves, which in turn means there are more substitute teachers than usual that week. More subs and fewer students means that many schools don't bother introducing any new material that week (at least in the lower grades). And if they don't introduce any new material that week, more parents (like my wife and me) feel freer to pull the kids out of school, and so on.
Anyway, the week starting the 3rd will feel pretty normal at first, but will start to thicken a tiny bit by Tuesday, by Wednesday things are a little fuller, by Thursday you can tell something's going on, and by Friday it's tough to walk through Fantasyland.
In other words, if dining at specific places is important to you, make those ADRs.
A big car repair and a new central air conditioner mean that we'll probably cancel our reservations for that week due to financial constraints. Lucky for you ... one less set of funny accents to put up with.
