I remember being in the World Showcase when it opened but noticed Kidcots weren't open. Do they all very or is there a specific time they all open at once?
When we were there the 1st week of May we started going around the WS when it opened at 11am. We started in Mexico and all the kidcots where open when we got to them. It may be different at other times of the year but that was our experience.
Every KidCOT station opens at 11 AM, right as the World Showcase opens. They are open almost all day; they usually start to pack things up at about 8:30 so that no one misses IllumiNations!
The kidcot-- are stations where the children decorate their masks. They also get their passport books stamped there. Along w/ being able to interact w/ person's representing each country. My son learned quite a bit at these stations.
