Hello ready2sail, and welcome to cruise-chat!
We are just like you -- we travel with our son and don't necessarily want to leave him with a kids program. We've found almost all the cruise lines to be pretty good at providing entertainment the whole family could enjoy together, particularly NCL, Carnival, and Princess. I'd also give Royal Caribbean another look, specifically their newer ships, as they've expanded their activities the past couple of years.
Many lines do have adult-only shows, yet those generally begin later in the evening.
What itinerary are you considering, and what length of cruise?
