Ahoy, Scott!
Thank you for coming to the Disney Parks Moms Panel with your question! On every cruise, my husband and I head to
Palo, the adults-only restaurant on the Disney Cruise Line ships, for brunch. It is one of my favorite "treats" to myself!
There are actually two answers to your question. First of all, if you would like to eat with these friends for ALL of your meals on your voyage, you will want to call DCL reservations at 800-449-3380, with your reservation number and your friends' reservation number. Ask them to "link" the reservations. This will allow all of the people to show up when you are trying to book Adult Dining or Port Adventures.
If you don't want to link your reservations, to book Palo, you will each need to go into your own reservation on the Disney Cruise Line
website and try to reserve the same time. Then, once both parties are onboard, you should all head to Palo to ask them to seat you together for your meal. This should easily be accommodated.
I hope this helps with your cruise planning and that you enjoy a lovely meal at Palo. Please let me know if you have more questions arise as your journey gets closer.
Happy Cruising, Tracy V.
