Yay! I remember when I first booked a DLR trip and got all my packet stuff. I think I read and reread everything at least a dozen times.

Getting AP's is so worth it, as long as you'll go at least one more time in a year. Have you decided when you're going to upgrade? I would say be sure it's after EE but that won't matter since you're onsite. So I'd do it the first day so you can get the 10% on food. That adds up quicker than you'd think, especially if you're doing any character meals.
