We bought the Abbey Vogue 650 (2009)6 berth with twin bunks to the rear whcih can be set up in different ways, side bathroom with separate shower, it's got plenty of room, the rear can be shut off to use as a changing room, although I find the bathroom is adequate.
It has an end dinette so the kids can play colour or just chill out. It was actually the kids who persuaded us to buy it, they love it.
Unfortunately Swift stopped making them but these below have the same layout.
I used caravanfinder website to look at different layouts before spending hours driving to different dealers.
Hope this helps and good luck.
