Ahoy there, Cathy!
Welcome aboard planDisney! The first time I cruised aboard Disney Cruise Line, I couldn't wait to book my next cruise, so I'm glad that you are looking forward to another cruise soon!
Currently, there are no Special Offers for 3rd and 4th Guests in a stateroom to sail for free. I recommend that you keep checking the
Special Offers on the Disney Cruise Line website. There are some great
Canadian Resident offers at the moment (subject to change without notice), so perhaps that offer will work for you and your family.
I also recommend keeping an eye on the
Disney Parks Blog as they often are the first to announce the latest news on Disney Cruise Line, including special offers, itineraries and updates.
Cathy, I highly recommend purchasing a
Future Cruise Onboard-Only Booking (sometimes referred to as a Placeholder Booking) on your next cruise. This special offer allows you to save 10% off the prevailing rate (as quoted on DisneyCruise.com) of a future cruise. I book one every time I cruise, just in case! If I end up not using the booking, the deposit is fully refundable.
I hope this information is helpful, Cathy. Please sail back by with more questions; we love helping other Guests make the most of their Disney Cruise Line vacations!
Wishing you many magical memories,
Shannon
