Just back from a week long stay at the Wildflower Lodge. We had a big group, with five families and kids ranging in age from 7 to 12. The Lodge is set up very nicely for large groups, with plenty of common area / gathering space, and areas for privacy as well. The Lodge has been recently updated and includes high end appliances, electronics (Sonos, Apple TV), furniture, fixtures, etc. and is very nicely decorated.
The location worked well for our group - situated nicely between the resort (7 minute drive) and the town of Jackson (15 minute drive). The kids loved playing outside and in the hot tub when they weren't skiing.
One of the best parts of our stay was the service, from the initial inquiry through the final departure. And it was such a treat to wake up each morning to freshly made breakfast and to return after a day of skiing to fresh snacks, both offering one less thing to worry about on vacation. Meg (Property Manager) and Lauren (Chef) were both exceptional. Highly recommend the Wildflower Lodge if your considering something in the Jackson Hole area.
