We stayed here 4 nights as we wanted to see east side of Glacier. This KOA is overdue for maintenance, sites in poor shape, unlevel: was very hard to level our coach. Lots of dust from the staff who seem to want to race around on 4-wheelers during the day on poorly maintained interior gravel roads. Forget about all their advertised ratings for: "Presidents awards, most romantic spot, most scenic, etc." The facts and condition of park to do not support these claims. This park might work for a 1 or 2-night stay only because you want access to St Mary side of Glacier Park. Or stay in West Glacier.
We stayed here two nights and were very pleased with the large, very wide size of the pull through sites. Has a very helpful staff, and the free breakfast was great. Good Verizon coverage, and Dish-TV coverage. Would stay here again.
