I am planning a Glacier NP trip in August without a car (not used to driving in mountain terrain and really wish to avoid it). I plan to fly to Kalispell, get a shuttle to West Glacier, stay there a couple of nights, and then head to Many Glacier hotel where I have a reservation for the next 3-4 days, before heading back to West Glacier and then catching a return flight from Kalispell. This seems mostly doable to me given that I mainly want to go day hiking around Logan Pass and Many Glacier, except for the issue of moving between hotels.
I have been looking into options for getting from West Glacier to Many Glacier and back. I had considered the train to East Glacier + East Side Shuttle (with the advantage of being able to enjoy the train ride), but Amtrak timeliness concerns + lack of reservations on the East Side shuttle (I checked with GPI) make me wary.
The other option I see is to take the NPS shuttle from West Glacier to St. Mary's and then transfer to the GPI shuttle that goes to Many Glacier. I am wondering if using the NPS shuttle for this purpose seems a feasible option given that I would have one moderately sized piece of luggage with me (likely a 20-24 inch wheeled bag) in addition to a daypack. On this point, I have been unable to find information (the NPS website does say that it would be difficult for people with many pieces of luggage but that does not apply here). Any insight on whether some visitors successfully attempt this means of moving between hotels with limited luggage would be most appreciated.
I am also planning to check with GPI to see if I can take a bag with me on a Red Bus Tour and leave it midway, since that might be a convenient way to get between hotels.
