Might be able to do you one better if you aren't married to the idea of Premier passes.
I have an RV ticket that I bought thinking that my group would be using it. Turns out about 80% of the girls didn't get their tickets in time. Here's a little bit about the RV pass:
------------------- GOLD RV $295 UPGRADE PER RV
Oversized spaces (25’x50’) Close to the Amphitheatre Not in the main campground Short walk to the main gates Free showers Sorry, no RV hook ups available Pump service will be available for an additional fee -----------------
I feel like that's a pretty decent amount of space, and would work out to less that you'd pay for 2 premiere spots.
Let me know if you're interested, or if you need any other info. I live in downtown Vancouver, so meeting up shouldn't be a problem. I'm asking for face value ($295USD + tax), so you're not getting ripped off.
