There are several options. The most convenient/least expensive options is Teton West Motel. Teton Spring Lodge is the most plush but expensive option in the valley. It has the most amenities but is also a little bit of a drive, from the reception but in the same town as the Rehersal dinner. Teton Valley Cabins are also a nice option with a rustic vibe. If you dont mind a little drive, Teton Valley Resort is the cheapest option....if you dont know you need to google "Dry Cabin". Airbnbs/VRBOs are worth considering. Especially if you know other guests and would like to plan a group trip. We'd encourage you to look in Driggs when searching for properties.
While we love your little ones, our wedding is going to be an adults-only event. We understand this presents further logistical challenges and appreciate you making arrangements ahead of time.
