Jennifer,
Good hints. Can I ask - your signature line show you have younger kids... my DD is 8 (will be 9 in February) - how do your kids do on the evening hours?
In January, I am going with just my DH and DD8 (almost 9). I was thinking of trying MK EMH evening hours - just to see if it works. Since we are at BWV, I thought about trying DHS evening hours - we can just walk back to the resort if she gets tired or if it seems too crowded.
I like to try "new" things each trip - and the last time we did evening hours was 2 years ago - and we lasted an hour - total bust - long lines, whiney 6 year old. But, maybe we did it wrong...this time, we will go there, eat first, then try to do some rides or just walk around and enjoy...

We try and take it easy during the day if we know a late night is ahead. We relax at the resort pool and/or have a nice late breakfast. BW has an amazing pool. Take advantage of it. Also, you could maybe walk over to Cape May (BC) for a nice character breakfast (Minnie, Chip and Dale, Goofy and I think they recently added Donald Duck). Get to the park refreshed and ready for an evening of fun.

We've been to an EMH (PM) before that ended at
2 am and our children were
ALL still awake. Now, the boat ride back to VWL they
DID fall asleep. But, in the park they were alert and ready for fun. You can't burn the candle at both ends, on any day at WDW. So, I wouldn't expect kids (or even adults) to last all morning and night at a park. Even on regular days, we head back to our resort mid-day for a break. It makes for happy kids and sane parents.

sad2: A lot of people
DON'T do this because they think it will take too long to get back to their resort and then back to the park later. It really doesn't take that long. Also, sometimes it is nice to get back to your room and take off your sneakers and get those gross socks off. A fresh pair of socks can make your feet feel so much better too. Also, my DD6 doesn't like public restrooms. So, it's nice to get back and refreshed too. Staying on-property has some major perks. I put some more cold water bottles into my bag and then off for more Disney adventures . . . )
FYI: When we recently went "Home" to WDW, they no longer did the wristbands during EMH (PM). We showed our KTTW at the entrance of the rides. Now, I heard about this previous to our trip and thought it was going to be a major pain. We are a family of five and I was worried about having to keep taking out and putting away 5 cards. However, it wasn't too bad and the line went pretty quickly.
Have a magical trip!
