We had a great time in Valemount. A much cheaper option than Jasper for a larger group that all want to stay in the same place and cook/eat/hang out together. Beds were great, kitchen had everything you needed. Gorgeous building. Large parking area where we played a bunch of games. Lots of dishes, cutlery, towels, etc. 20 mins from Mount Robson and lots of cool hikes. We weren't with people who bike but spoke with a lot of people who were taking advantage of the bike hill and this place is set up for it. 3 Range Brewery was a nice escape from the kids.
No AC but lots of fans and good window covers used properly and you wouldn't know it (we were there when it was 33 deg C).
