I'm looking for some advice from folks who've been both to Glacier and Yellowstone national parks who can compare and contrast them for me as my family and I try and decide which to visit this summer. Along with the variety of topography and range of wildlife there is to see, I'm most concerned about crowds -- particularly since we have to spend our week vacation there either during the last two weeks in June or during the first two weeks in August.
My wife and I drove out to Yellowstone and the Tetons about five years ago (we're going to fly from the east coast this time), and it was one of the greatest vacations of my life ... that said, we were out there during the first week in June, and the crowds were minimal ... can anyone speak as to the differences during peak season between Glacier and Yellowstone? And, given that there are seven of us, can anyone recommend a rental cabin in either place that takes weekly reservations? Any thoughts will be appreciated!
