Planning to be at Bethany with two boys (ages 4 and 6) and an infant (6 mo) next week. I wasn't expecting to have beach days but the extended forecast is showing temps between 38-58 degrees. The place we are staying has an indoor pool, I know we can find indoor mini golf, we can still do Funland in Rehobeth and will will bundle up and still have outdoor time at parks etc....any other suggestions for indoor fun? Are there bowling alleys, movie theaters?
