Most large venues have a little known service whereby they will "upgrade" the people with the shittiest seats to better ones, either by request or they'll offer it outright. The industry term is "relocate" or "relo". Shortly before showtime they will have a list of any unsold seats and make those available for "relo". On Sat after getting our tickets we immediately went to Guest Services and asked for a relo however they didn't have anything available. We went back about 15 min before showtime and they told us they released the relo's and there should be a guy in the nosebleed area offering trades. Sure enough right outside the entrance to our section there's a guy there at a table with a small stack of tickets available to trade. We gave him ours and he handed us 2 lower bowl tickets. Even the tickets themselves had RELO on them where the price is listed. Score! I've done this one time in the past when I ended up with crap seats and will do it again at the next Stones show in 2 weeks if necessary.
