I've only been to US/IOA twice myself, so I'll share what I can.
US/IOA's Express Pass is similar to WDW FP, with the exception that you don't have to go to a machine to get a FP. Being you're staying at HRH, you room key is your Express Pass. And unlike WDW, you can bypass the lines as many times as you want. You won't get to the front of the line, but you get to the front rather quickly.
As far as rides go, there are several that are comparable to WDW. If you're a coaster fan like me; IMO, you'll find the coasters here to be way better than the ones over at WDW. Not saying the ones over at WDW aren't good, just saying I just so happen to like the ones' at US/IOA a little better. Don't want to get flamed or anything; but again, that's just my opinion. If you want to get a feel of what rides are available, check out Universal Orlando's website (
http://www.universalorlando.com/OverviewPages/TP/themeparksoverview.aspx) to see what rides there are. Then you can go to
youtube and watch some of the videos.
The site will also give you some insight to City Walk and the resorts, and what they're about. We ate dinner at City Walk after the parks closed, saw some live bands and just enjoyed walking around seeing all the different shops.
Sorry I can't be of enough assistance for the resorts though, as I've never stayed there. Trying to see how I can work that out for next year.
As
Purseval said, just ask and someone will answer your question. HTH.
