Did you do the 'art of the theme show tour' (tour of design elements on the ship) or the 'anyone can cook' classes (observe a recipe being made and try a sample)? Those are some of our favorite adult only things. We do like the family activities as well, so we had fun with the midship detective agency, mini golf, character drawing classes, napkin folding, character meets, etc. We didn't get to the adult entertainment offerings last cruise, but enjoyed them on other cruises, like a magic show and a music group in an adult only club in the evenings.
If you prefer Virgin, it may be that you've found 'your' happy place. Everyone has different preferences. It does sound like you enjoyed your
Disney cruise, just not as much as your previous cruises. It's good to try other ships, you learn what aspects of cruising are important to you.
