Ahoy, Cynthia!
Thanks for sailing to the Disney Parks Moms Panel! You are planning my absolute favorite type of Disney vacation!
Disney Vacations by Land and Sea are perfect because you get to experience all the excitement at Walt Disney World Resort as well as an adventure-packed voyage aboard Disney Cruise Line. Also, I think beginning and ending your vacation at Walt Disney World Resort is a great plan!
Previously, Walt Disney World Resort hotels have allowed Guests to leave their cars parked in the Resort parking lot during their voyages with Captain Mickey! I highly suggest calling your particular Walt Disney World Resort hotel and mentioning this plan to them just to make sure this option hasn't changed. Once you arrive at your Resort, be sure to mention these plans while checking in so the Cast Member is aware of the additional days your car will be parked in the parking lot.
It sounds like you're planning on taking
Disney Cruise Line's Ground Transportation to and from Port Canaveral! If you haven't done so already, make sure you book ground transfers in advance so you're all set to be picked up from your Walt Disney World Resort hotel and then returned back to your Resort hotel after disembarking the ship.
Thanks so much for asking this excellent question! If you have any more questions, please don't hesitate to visit us again!
