There is a new activity center in Cancun that offers classes for kids of all ages (1 year to adult). The website is www.creartik.com. They have arts and crafts, painting, acting, singing, cooking, music appreciation and a lot more. The courses are not free and the prices fluctuate depending on the activity. Most activities are an hour long. Very clean places with friendly employees and teachers. Since there isn't too many things for kids to do here, this might be a good option. (***I do not own or have any financial gain for recommending this center).
