Grand Teton and Yellowstone each have their own lodging logic — inside the parks and gateway towns, and Jackson Hole is its own decision entirely. Here’s the quick version: staying inside the parks means less driving and better sunrise access, but books up to 13 months out and comes with no AC or WiFi. The gateway towns (Jackson, Gardiner, West Yellowstone) give you more restaurants, easier booking, and a home base if in-park lodging is sold out. Pick your guide below based on which part of the trip you’re planning.
