We own at Fairmont. You have a choice of Hillside, Riverside, Riverview(new) and Mountainside. We like Hillside, Riverside Mountainside in that order we haven't stayed at Riverview.
I would not do a trade for that time of year, you should be able to pick up a Getaway for around $ 279US for the week. Hillside have a beautiful view of the valley and are lovely big units. Riverside are very nice but getting a bit dated and are right on the golf course with lovely views, close to the rec centre etc. Mountainside are the original timeshares, they are cedar, so more rustic, the two bedrooms sleep 6 and have the master bedroom up stairs. They feel more like a cabin in the woods. They are also very nice but have no lock off. At Hillside the lock off side is very comfortable for four people the Riverside lock off sleeps four but really is quiet small.
Hope this helps.
