I know this is going to be worth it once we get there, just to see the look/magic in my kids' eyes, but I'm getting seriously frustrated planning. I dont think I've ever had to spend so much time/energy/headaches on planning a vacation before in my lie.
It's a lot of information to process, but as a first timer, you've come to the right place. The people here will give you the very, very best advice, and as you can tell, they LOVE giving it.
With ADRs, having a good plan is important, so you can spend more of your vacation doing the things you want, and less traveling between parks. You'll be loving yourself for going through this headache now, thus your vacation goes smooth.
