I am with all of you - most I have paid ever ($318.)
We are staying at Boardwalk. While I always love having a rental car, no matter what DVC property I stay at, I always take the bus to MK. So for this trip, we can walk to Epcot and Disney Hollywood Studios and take bus to MK. This only leaves AK and Disney Springs for a rental car. Heck, I may just uber those destinations and use Magical Express for airport transportation.
