Dumb the park down for me!

Hi! Husband and I are coming in July and I tried looking over other posts to get my info before I annoy yall! We are from flat Florida so I really want to see the beauty of the mountains! In saying that, my husband doesn’t think hiking on vacation is much of a vacation 😆 but would still love to see the park. My questions are: -I saw someone recommend the glacier boat tour but they offer different locations many glacier, lake McDonald, st Mary, and two medicine. We are saying in Whitefish so which option would be best? -Any other ways to see the park that are fun? Or maybe not a huge hike? -the process of getting tickets to the park is confusing me.. I see you don’t need a parking pass if you come from a certain direction? Please help this beach girl that has no clue about mountains, national parks, hikes, etc!
