We were at
HHN on Sunday for the tail-end of our honeymoon (we're romantics, I know

) and we were staying at Hard Rock. We didn't know the express passes had been sold out, but when we went to buy them on Saturday, the day before, we were informed that they keep some set aside specifically for the people staying at the resorts, so we were able to get two even though they were otherwise unavailable! So glad we did, too, because those lines were awful otherwise. If you can, try and get a night at the Hard Rock or one of the other resorts if you really need those passes, and I do recommend it!
Because we were there early, we were able to hit the first four nearest houses (Nightmare on Elm, Psychoscareapy, Vampyr, and Chainsaw Massacre) without even using our express, since they're only good once at each attraction. We finished up around 10:30 with those four available on our passes, so we grabbed a couple at random out of the regular line at the Freddy House and gave them our passes. They were so thrilled! And I'm glad they got them too, because all the waits were over an hour by then -- no way they'd have made it through waiting in line! If anyone else has the opportunity to do this for someone, I really encourage it, because it really lets you make someone's day. And after all, we weren't using them!
