My husband and I are going ot Stratford for the weekend in September (I wish we could go fro longer to explore). The shakespeare festival is going on so we will be seeing a play. There are a lot of lovely hotels and B&B's and the prices appear reasonable. It's 3 hours from here and is definitely and adult thing. Check out the StratfordFestival online - it may be something you can do.
Good luck and enjoy
