If you have a car and are staying in mostly studios, then the delta between the TOT and what you save on parking is likely a win.
Unlike WDW, there is no free parking for non DVC guests staying at the Disney Hotels in CA. Even at Grand Cal you get to pay 40+ bucks a night for the privilege of paying 700+ a night for your room. Sure, VGC owners and fans will say you get the best of both worlds staying there (count me in that group too). IMO the huge number of studios available for VDH is a strength and when me and my family save a ton on parking fees, it takes a good chunk of that sting away.
