I was very happy with the overall value that I received going to Treetops. They really seem to have found their nitch of catering to families and not trying compete with the larger resorts that surround them. There must have been a management change in the last two years as their operation, staff and cleanliness has improved a lot.
Our family went tubing and had an absolute blast. Quite a value at less than $10 per person for a FULL 1 1/2 hours.
If you're looking for a resort with hills that are not imtimidating for those in your group that are new to skiing but still with its fair share of challenging terrain, it's a great place to go.
