My mom (61) will be coming along with us. It will be her first cruise and thought it would be nice for her to meet up with some others traveling as a single. I know they have lunches and singles meets on board. I thought I read there are a few bringing their single parents.
Yes, my mom is coming along. She just turned 75 in May. She's into a slower pace these days, but enjoys playing bridge if there are enough numbers around in that category. It's more her 20th cruise or so, so she's more experienced than your mom (and me), but 1st Disney cruise.
Don't know about the events, but I'm sure we'll hear about it onboard.
