I did this for the Christmas show last year. It was fun! There were lots of adult skaters (40% of the total). We were not alone and had a terrific time.
The change room stuff was a blast too, though a tad noisy at times. Putting my hair into a bun for the first time in many many years was hilarious. I knew how because I sometimes do my daughters' hair, but on myself was too funny.
My kids & husband were incredibly proud (relieved) that I didn't fall. The more competent skaters were trying tricky stuff and did fall. It showed the wisdom of performing what you do best, not the flash stuff that may not work.
