We'll be there around the same time and I'm looking for touring plans as well. With the buy 2-get 3 day pass we've decided one park per day (probably will do IoA twice, but we'll decide after day 2) and no express pass.
It won't kill us if we can't do every ride, since DD and I have only been there once 3 years ago, and hubby is a 1st timer. Back then we found the walk between parks was a big time waster, hence the one park per day choice. And we only did the 2nd morning at US and went back to IoA for the afternoon. Harry Potter and Seuss's Landing were our faves in all of Universal.
I did find a couple of apps on
Undercover Tourist but I'd like to go with a touring plan -- which is so not like me, but without the express pass I think we'll need it for Pres Week.
