Considering the Courtyard By Marriott Phoenix North in Phoenix?

Arcosanti - Urban Architecture Laboratory by DrexelDragon
This is a Phoenix must see although it should also be under Off the beatn path, because it's about an hour and half's drive south of the city. Arcosanti is an urban sprawl architecture project that focuses on arcology. It was the idea of Paolo Soleri I can not explain arcology or Arcosanti as well as the its website (check for the link below). Yet, I can say that I wish my camera was working the day I went there, because this place is really cool. It's idealism at its finest. The work is all done thru donations and through the sale of the Soleri windbells (really are fantastic and sound great - make great gifts).
If I was back in Phoenix and could only choose to see Taliesin West or this place while I was there...I'd choose this, Arcosanti.
