I've actually heard that the new location is a touch warmer (lower altitude?) but being closer to the coast less likely to get freaky hot (like it did at the old location a couple years back). So hopefully that won't be a factor. But to clarify, there isn't a real "dorm" option this year. It's either BYO tents or the 4-person tent "dorms", which are fixed-frame canvas tents with floors, decks. and electricity. So outside of plug-in heaters (which I've heard Matthew consider if the weather reports sound chilly), it's really a choice between privacy and a few amenities (floor, bedframes, deck, etc).

Hope that helps...
