Thank you Dave. Didn't realize the season was such a short one. It seemed like there were several resorts so I had figured, no problem. We already had a week booked in Idaho so we had figured just adding Glacier to it. We usually go for at least two weeks when we fly somewhere just to make it more worth the trip.

Bart, the key to seeing the Glacier National Park area is the weather, and snow accumulation. Elevation is pretty high up, and it's all mountainous country. It can (and often does) snow into June. Then it can start up again around the first part of September, and snow until the following June. Snow in July and August are not unknown. Obviously, snowfall seriously impacts the ability to get around in the park. There is only one main road through the park, and if it's closed, well, it's closed. It's all well and good to see the perimeter area, but the best parts of the park may be inaccessible because of the snowpack.
The "Going to the Sun Road" is the part of the one road through the park that goes up and over the Continental Divide, connecting the West and East sides of the park. It is an incredible drive, and is the main reason many go to Glacier. Plowing it to get it open to traffic is often interrupted by snowfalls, snow slides, and such. The road often isn't fully cleared until well in July, and by late August, the snow starts up again, and the road closes for the rest of the year.
There are a number of timeshares in the area, that's true. But to reserve a week during the prime visiting season is a premium. Early September is still considered good travel time, (although the GTTS Road may be closed by then.)
If you're locked into that week, my suggestion is to try and rent directly from one of the resorts or a hotel, rent from an owner at one of the resorts, or see if a mega renter on Tug can help you out. (Ron Parise is highly recommended; there may be others.)
Glacier is incredible, and is well worth seeing. My reservation was made two years out, and the first week of June was as good as I could get. There was a lot of snow on the sides of the road, the GTTS road was still closed, and parts of the park were not yet open. In spite of that, I'd go again anytime. it's THAT nice there.
Good luck!
Dave
