We had an OUTSTANDING experience with Campervan North America! We were 1) keen to have a great outdoor experience in the Glacier Park area, 2) being mildly wimpy wanted to glamp, rather than camp, 3) very keen to get insight into the sprinter van lifestyle but 4) not keen on spending $5k+/wk for some of the decked out sprinter vans.
Campervan North America hit all of our requirements. Tom and Kathy were incredibly pleasant to deal with and very helpful. We rented the Bunkhouse to sleep two 50+ year old parents and two teenage girls. We got two 500 mile packages (returned it with about 10 miles to go), kitchen gear (propane tank, two burners, plates et al for 4), and sleeping bags. Blackout screens for windows were included and would have been dark enough to develop film (dating myself?) except didn't cover the very useful (really! both for venting and for white noise (birds in the morning are VERY noisy) ceiling fan. The van did not have running water, but between 5g water jug (part of kitchen set up) and facilities at national park camping facilities, was not a problem at all.
Roughly speaking was about $200/night for both car, lodging and gear (not including gas which was about 16mpg x 985m = about $160) - compare that to a rental car and lodges and it was a great deal. We stayed a few nights in Glacier's classic lodges - were to do it again, would stop by for a meal, but probably stay in van for the night and save the money - lodges are more expensive, louder (very thin walls), and not much better in facilities outside of the very pleasant public spaces.
Van was a great way to camp - nice balance between not having to fold up a dew covered tent, nor isolated in a mega-RV. Sleeping was comfortable for the four of us. Girls had privacy screens for their bunks to give them their space, we rigged up a privacy screen for driver seats so I could read in the morning before the rest of the crew arose. At 19' was allowed anywhere in Glacier (over 21' and can be curtailed), and still easy for a novice van driver to maneuver.
Strongly recommend Campervan North America. Really enjoyed the experience and very pleasant/helpful service.
