In the tier 3 hotels (somewhere below a full Sheraton/Hilton but above a Motel 6, etc) Hampton Inn ranks just below Four Points by Sheraton for me. When I stay in Lethbridge I choose the Hampton Inn on the east end of town just off highway 3. Newer building, nice rooms, clean, friendly staff, and a better than average breakfast included (versus other tier 3 breakfast-included hotels).
Reasonably quiet rooms with good finishings. I'll definitely be back to Lethbridge and to the Hampton Inn.
