Yea, unfortunately your thoughts on Pacha are dead on. Here is an excerpt from my 'uninteresting trip report' [
http://www.spotlight-forums.com/showthread.php?t=75570 ] (yea, we went on "commercial central" night, my concession to my buddy that came on the trip with me)
And this was early in the season too !! I'm sure it was worse as July/Aug hit. Basically, the VIP section is MUCH bigger than the dance floor, which is ridiculous. It's so unbelievably rammed, that it's unpleasant, regardless of your taste for the music. Not to turn anyone off, but Betty's description is dead on. The club will get to you. Expected to be rammed, expect to have no room to dance.
That's why I ended up saying if you really feel like you must do Pacha, strongly consider VIP.. not because it's cool or you are cool, but because it's the only way you will not want to kill yourself. And presumably you are there to dance, not defend yourself from getting knocked over while having your arms plastered to your body by all the other sardines that got crammed into the tight can of a "dancefloor" (that's in quotes because they call it a dancefloor, I call it a hellhole)
