Vacation suggestions for white water rafting in East Tennessee.

Suggestions for:

Where to stay: I want it to have a nice outdoor pool. Bedding cannot be bedspreads, must be a conforter triple sheeted.

White water rafting: suggestions for a medium level, I have never done it before, I want it to be fun, not scary.

Other activities: Looking for some horseback riding also, beginner level.

Thanks.
