Saskatoon Inn is the one that's absolutely closest to the airport. Its a nice place, but definitely not near any of the 'attractions' Saskatoon has to offer such as downtown or the University. For parnel's benefit, I believe its one of the only major hotels in Saskatoon not unionized.

The Delta Bessborough is probably the most spectacular hotel, on the riverbank. The Sheraton is downtown about a block away from the Bessborough, and its a nice hotel as well (for parnel's benefit -- partially unionized).

The Raddison is a bit further away from the immediate downtown core and the University, but still pretty close. Physically its pretty nice, but my experience has been that the service is poor.

So yes, as indicated here, you really can't go seriously wrong as long as you avoid the "hotels" on 20th street. Yes the Barry Hotel might charge $5 per night, but its not a nice part of town to be in after dark at all.
