I just bought tickets today on the internet for the Trenton, NJ show. Center rink, lower level, row EE. I'm happy with the seating. The theme of the show is Time.
Advance Tickets are on sale via the Net until November 14th. Beginning November 17th, they are available at the box office.
I also checked the Philadelphia, Atlantic City and NYC shows and the seats available are good. I was actually surprised that NYC had such good seats available until I realized that the show is on a Thursday evening in NYC. It's typically on a Saturday; so, I guess a lot of non-Manhattenites have decided not to take their kids on a school night.
Also, if you visit the site, there's a chance to win a trip to SOI Canada.
Edited to add: The prize is a trip for 2 to the Vancouver show. Contest details aren't available on the site even though they say it begins in November.
