I say that it is totally worth the extra few bucks per person (it is $100 for a whole team after all.). Short waits for air (Bonus), a place to kick back and relax between games, food and ice cold water, shade for the sunny days, a roof over your head for the other days (if we don't talk about it it won't happen...ssshhhhhhh), a very friendly and helpfull security person. You almost step right out onto the fields for play. Chance to mingle with some kick *** people and players.
If I had the skill to play in the GPL I would definatly jump all over the VIP section at every event, it is worth every penny.
If you have any questions ask around or drop me a line. firstname.lastname@example.org
Oh, check out the pic of me playing with the German Shepard at the last GPL at myspace.com/thegpl
