Hi all. We are doing an RV trip to Great Smokey Mountain NP the end of March with three kids 8-14. I would appreciate some recommendations of what we should see & do. I read it can be chilly in the mountains. I wanted to know how chilly! and what are some realistic expectations of what we will be able to do and see at this time of year and what are some rainy (or too cold to be outside for anything length of time) ideas as well in case we need those. As first time RV renters, I welcome any advice on the RV experience as well. Thanks so much.
