The purchased express passes get you in the same line as the hotel guests. The only difference is that the purchased passes are only good for one time on each ride.
Not sure if there are more expensive passes that get you more but I know my husband had checked out the plan when we were there a few weeks ago (stayed at HRH) to see what the cost would be if staying off-site. The unlimited use with the hotel room key is so worth the extra cost of the room, which isn't that bad with the
AAA discount.
