Just to throw an option out there...
Look at something like a Catalina 313RLS. It has a rear entertainment area, and an small slide near the bedroom with 2 bunks. It's separate enough, but not an enclosed bunkhouse. You get a kids area to sleep, and still have a larger rear entertainment space. (Premier also made this exact Floorplan, I was in one at an RV show but cannot find any trace of one online)
Also, in my opinion, an outdoor kitchen is a must have for me. I would never buy an RV without one. It's the single best feature on my TT and I love it. Some don't like cooking outside, I do. We've never even used the inside kitchen for meals.
