Most tickets are priced at $425. The $1200 tickets are for people who can afford them but couldn't get them at $425. Some of the $$ from the $1200 ones goes to support the low-income ticket program fwiw.
I will say, if using a portapotty "ruins" the experience for you, you're going to be better off going to an event where you can stay in a hotel, vs a big camping trip to the desert.
