40th anniversary weekend getaway...ideas needed
 

My inlaws will celebrate 40 years next June. We'd like to send them on a little weekend getaway somewhere within 3 hours of Philly. They live across the river in NJ. Was thinking about a B&B in Cape May. Can you suggest any other options?

They enjoy shopping, fine dining, museums. They aren't interested in nature or wine. They don't really "do" shows since she has a bad neck.

I guess the Branywine Valley area would be an option too with passes to Longwood Gardens.... Or St. Michaels Maryland?
