I had a chance to sit in the Dream Seats for the Sep 11 home opener last year when we beat the Giants and loved EVERY second of it. I was in the endzone, left side. The action when someone is about to score is so amazing, but it has hard to follow action at opposite end zone as you'd expect. You also get a few additional perks like club access (including the much much shorter line to get in stadium) which is a really nice benefit over cheap seats. I actually think they are priced about right -- they aren't the best seats in the stadium but the whole experience is pretty darn cool.
Of course there was one MAJOR disappointment: Kerrigan's pick 6 happened on the right side of the endzone, not where I was
