We were at the HR Live for Nickelback in Aug. Not sure how your show is set up, but for nickelback, the whole floor was GA, the upper level has high tables on the sides, which I was told you need to reserve the whole table(at that time they seated 4) The back of the upper level had the regular reseved seats, thats where we were. You can see everything fine from there. It is a small place. I don't have the number handy, but I called HR Live directly, and the gal on the phone was very nice and explained the seating well. I was even able to order the tickets for a will call pick up. (didn't want to risk them not showing up in the mail as it was only a few days out from the show) Anyway, the day we got to the parks, I went to the window & was able to pick up the tickets the day before the show so I didn't have to deal with it the day of.
Sorry to hear of your expirence at the HRH, we have always had good luck with them, great service and quick check-in, etc. The location is great for the HR Live. Hope this stay is "less eventful" for you.
