Amazing place, staying at Hosmer Grove was a good choice if you're planning to camp inside the crater overnight since in the morning you can watch the sunrise and then plan to hike in. Sunrise is amazing, but extremely crowded, you'll fight throngs of people to get a decent view. Sunset is also quite beautiful, and of course much less crowded. Downsides of going the cabin route: 1. they are often booked the same day they are released, very competitive to get a permit, 2. you have to wait until the main office opens to get your cabin permits, so we had to backtrack after watching the sunrise instead of directly hiking in, 3. the provided "firelogs" are pretty sad, essentially compacted sawdust that are difficult to start and burn through quite fast so you have to tend the fire quite frequently. Positives of the cabins 1: less gear to pack in since you'll have a roof over your head and there is plenty of cooking gear and a propane stove.
