My mom, sister, and myself are heading to the World in 2014 to do a celebration trip to commemorate 20 years since my sister and I's first Disney trip. Mom and sister will both drive as they already live in FL, I however will fly in. We are considering staying at Caribbean Beach for part of our trip, and then transferring over to Yacht Club part way through as they're the only two resorts we stayed at as kids, so basically it would be a trip down memory lane sort of thing. How does this work? We're going to get Park Hoppers, and will have access to a vehicle for transportation. Will they transfer luggage, or is that up to us? And how will that work with the park tickets, do they just transfer over to the next Key to the World Card?
