Stopped here after leaving Glacier NP. I’m sure it’s crowded in the summer, but there were only a few others with us on this day in May. Bathrooms were super clean, showers were $3 for 6 minutes and you have to get tokens from the staff. I believe we paid around $28 since we were out of state, but it was worth it for us. The train is loud, but not a huge deal for us as my friend never even heard it in the night.
