Thanks for the all the suggestions. We cut a night off the Grand Tetons portion of the trip and found options at both Colter Bay and Signal Mountain Lodge, both of which were the least expensive of the places suggested during our time frame.

Check out Dornan’s. It’s under $400 and it’s centrally located in the park. Great Mountain View’s and a restaurant on site. I have stayed there both times I’ve gone to the Tetons.

We stayed at the Rustic Inn and it was perfect for us. We could easily walk to town, but it’s also incredibly convenient driving to the Tetons because you are just outside of town. They also had a shuttle service that could drive us anywhere. Great breakfast every morning too.
