We were on the magic, and there are family activities, like pool games, game show type things at night, a frog type race I think etc. We didn't do much of these as my kids loved the kid club and the regular evening shows. The navigator specifies all family activities by an F next to the event.
We did do one of the game shows in studio seas, but it was really geared toward older kids and families, my 5 year old would have been bored.
You should remind your friend that the kids clubs are free, and that you never know if a child will like it or not. They may be surprised how much their child enjoys interacting with other kids. The 5-7 year olds had lots of fun stuff to do.
My kids insisted on going the first night, I was a little hesitant, I was afraid it would be too crowded and would turn them off to the clubs for the rest of the week. Much to my surprise when I cam to pick them up around 10:00pm my 5 year old was learning to hula and loving it! It was too cute!
