This is our first trip to Disney. We saved a ton of money by flying in to a different airport and getting a car, so we'll have a rental car available throughout our trip. We're staying at Caribbean Beach Resort. How easy/difficult is it to park at resorts and parks? If we go back to our resort midday for a swim or something, could we easily then drive to a different resort for dinner? I imagine it's easier to park at the resorts than the parks. Do the parks have shuttles that run through the parking lot for people who have to park far away? Or would it be better to just rely on the Disney transportation?
