colinsdad, I just want to remind you that Universal Studios and Islands of Adventure have free Express Pass for resort guests. (I doubt, however, if HP will be included for a while. we were there when Rip Tide rollercoaster first opened, and it was not included yet. darn, I really wanted to ride that... NOT!

ok, but Nebo wanted to., but it was like an hour and a half wait.)
It's SO worth it to try it just once, staying onsite. it is such a short WALK to both parks. we stay at Royal Pacific (the cheapest) gorgeous pool! no slide, but a water fun area for kids. but Hard Rock(stayed there once) has a GREAT water slide at their pool, and pool hopping is allowed.
do not eat at the resorts, though.. pricey... but City walk has great dining venues, as well as counter service satnds.
