Over all, whether on or off site, that is the way to be, in my opinion. Time in the parks to me is absolutely no different on or off, meals are more flexible, and freedom to come an go always seemed simpler to me, but, like I said that is just me. I do things now out of necessity, like FP, and the occasional sit down reservation, but, mostly use counter service when I don't want to leave and outside establishments when I want or need a break from the parks. The later is at least once a day. After four days at WDW I am ready to go to a hardware store and see if I can find a huge mouse trap. Yes, I get sick of the Mouse. Blasphemy, perhaps... but, it might be that I have a limited attention span.
