I asked a yr ago or so but was checking again. Are there any campgrounds within a reasonable distance from frederick md that have an indoor pool. I'm thinking around 3 hrs away no more. Thanks.
My only thought was either the Poconos or Williamsburg at the Great Wolf Lodge. The campground's won't have an indoor pool, but Great Wolf Lodge is a year round indoor water park.
Can't think of any north of here (MD). Most are closed for the season. The closest ones that I know are open are down in NC, which is about 6 hours from you.
