It's my 2nd time here but the hotel is my 3rd choice. I prefer the Ramada or the Best Western in that order. However, sometimes availability and price point land you at your least favourite.
That said, it's not a dump, it's clean and the staff if you can get hold of them are courteous. If you're in Penticton for anything to do with hockey (eg tournament, camp, game) it's a perfect location. The Sandman is a block from the rink. But if you're not here for hockey the location is irrelevant.
My knocks on the Sandman are; the wireless is painfully slow. There is no tech help and repeated calls to guest services between 8 and 10pm were not answered. The fitness centre is 4 pieces of exercise equipment in a hallway. Expect to see guests rolling by with their luggage while you workout.More
