I think those of us without kids will be in the small minority on this cruise due to the Kids Sail Free offer.

I'll be there with my Mom, so we'll be 2 women - in 40's and 60's. I posted a while back looking for other adults-only travelers, but I think you're the first I've seen! This will be my 2nd ever cruise and first for my Mom, so we're similar in that.
I had booked this earlier, but re-shopped and booked at a discount while on my Thanksgsgiving Magic cruise, so we lost our Main dining and currently have 2nd seating, and are wait-listed for Main. I'm afraid we won't be able to get switched, and I'm not sure whether to even try to switch once we get on-board, but eating at 8:15 at night seem so late! Hopefully there will be some other adult-only groups that Disney can assign us a table with. My Mom and I get along great, but I'm looking forward to having some others to chat with over dinner!
