Hi B.,
Have you heard of Cherry Vally Lodge? My husband and I considered it for a place to have our wedding/reception, and it's beautiful. They have a spa, and some really pretty hiking trails, and tennis too i believe. They DO have a waterpark for kids though, so you'll probably have lots of families there with you. their website: www.cherryvalleylodge.com.
hope this helps!
