We have a PS205 '97. I have 5 kids and we all fit fine. It can be a chore climbing over the fat sacks when surfing or wakeboarding, but not really a big deal. I slalom 90% of the time, and when I go for an early morning run with just a couple of my kids I will pull the back seat, and I also keep the fuel at under 1/2 tank. Shedding a few lbs really makes a noticeable difference in the wake. I love my boat. I spent 15k and it came with a great stereo and tower, a trailer and cover, and a few kids wet suits and vests.
When I get the $$ I will redo the vinyl, carpet, and gelcoat. I've kicked around the idea of getting a new X7, but I think I'll hang on to this and put the $$ towards a used X35 for big water and family days when we just hang out on the water with no intent to ski.
