Couldn't tell you where the $600 thing is coming from. As I recall, that's the place Rachel showed me in the first place that she was interested in.
A few big details I'm seeing on their site:
Full beds: In reference to most hostels, I'd want my own bed due to the small size of beds. Full beds, though? I figure Rachel and I would be sharing a bed, meaning we'd have extra room.
Between her, Shane and myself, that leaves us with room for another four people in the room. I don't know if you're coming up with anyone else, but I figure a six bed mixed room between Linds, Mai, Katie, Matt, Shane, Rachel and myself would be pretty effectively bitchin' and it'd only be $56 a person.
I like this idea. Quite a bit.
