I fucking love sleeping on couches. Couches at night - hobo's delight.
Like Si said, air-mattresses always deflate under you during the night.
I read Eitje's complaints as:
"They wouldn't let me sleep between them in their bed, but at least they gave me a sweet couch rather then an air mattress or the floor. I played second fiddle to a cello and I'm surprisingly cool with that."
Anyway if you want a bed next time, Eitje, I'm 10 minutes from Philly and I've chosen my couch over my bed for general sleeping. Everyone's welcome at my place any time.
