The things that make Treetops a 5-star experience luxury resort are the staff and the surroundings.
Though I think most guests only stay a couple nights, I'd say my one piece of advice is to not over schedule yourself while you're there with activities that take place 'off campus' as it were. There is so much to do, see, and experience on the grounds of Treetops, that is really is like a sort of 'adult summer camp' in that you don't have to leave to get everything you need (but not in a tacky way like a resort-- just genuine natural beauty, basically). The food was really good, the spa is gorgeous, the bathrooms luxurious... Definitely more like staying in a wealthy friend's house than a hotel. The hikes were well marked and had satisfying destinations (bridal veil falls!)... didn't run into another soul on the hike except for two really friendly horses that followed us curiously for a portion of the hike.
The staff are incredibly professional and sincere, more like old friends than waiters/spa staff/chefs, etc. As my mother would say, 'a once in a lifetime experience!'
