请教：Yellowstone and Glacier NP 行程安排, Thanks!

Day 1: Drive Denver to Jackson ( 请推荐jackson 住宿)
Day 2: Grand Teton
Day 3-5:Yellowstone
Day 6: Yellowstone to Glacier NP
Day 7: Glacier
Day 8: half day Glacier
Day 9: Drive back to Denver

( 请推荐jackson, yellowstone and Glacier NP and 住宿)

Sounds like a good plan? Please let me know your thought.

另, Do I really need 3 days at Yellowstone or 2 days is enough, that way I can have one more day for Glacier )

Thanks for your input!
