Ahoy there, Chris! Thank you for visiting
planDisney with your question. It is a sign that your cruise is getting closer when your
advance booking window opens up, and you can book Port Adventures.
The
Exclusive Vintage Replica with Private Driver Port Adventure sounds like a great option to explore
Nassau, Bahamas. I am unsure of what the issue could be since you meet the party size maximum of 4 Guests, and your son meets the age requirements of 2 to 80 years old. To help you with getting your son added, you will need to
call Disney Cruise Line directly so they can view your reservation while you are on the telephone with them. I suggest calling first thing in the morning when the Help Center opens at 8:00 AM ET Monday through Friday or 9:00 AM ET on Saturday and Sunday.
If you have other questions or have more Port Adventures or onboard activities to reserve, the Reservation Specialists will be able to help with those as well. Chris, I hope you are able to get this figured out so you can enjoy this Port Adventure.
Adventure is out there!
