If you're staying in Kalispell, definitely Day's Inm by Wyndham, Kalispell. Naudem & Rebecca are great hosts! & the town is convenient to Glacier with everyhing handy you might need.
It depends on what side of the park, if you're camping and how big of a group. It will be busy so I suggest securing a reservation beforehand.
Weather will be at its warmest and cloud cover should be less of a problem than other times of year. I stayed in St. Mary campground and liked being close to both Going to the Sun Road and Many Glacier.
We camped at KOA..great campsite, a bit pricy . Weather should be good in August
