Hi there Catherine!
It's so nice to hear from you again. Your trip is really approaching quickly now!
Upon arrival at Epcot, be sure to pick up a Daily Times Guide which will list in detail, each and every Character Meet & Greet, live entertainment shows and so much more. You'll also find a detailed listing online. I've included the link to
Epcot's World Showcase for Saturday, December 28th and you can select the date you plan to visit by clicking on the arrows at the top of the page next to the date and calendar icon.
At each of the 11 countries around World Showcase Lagoon, you'll find
Kidcot Fun Stops where your children can participate in a crafting experience and collect stamps. To enhance your experience collecting around the world, consider stopping at Mouse Gear on your way into the park to purchase a World Showcase 'passport.' The link above will tell you the exact location of each Kidcot Fun Stop.
Now when it comes to entertainment, there are a few shows I find really capture the younger kids' interest and attention. My kids' favourites include France's
Serveur Amusant, Italy's
Sergio and China's
Jeweled Dragon Acrobats. Be sure to plan to watch both of these fun visits at some point during your day.
Wishing you a very Merry Christmas and a simply Magical time at Walt Disney World with your extended family Catherine!
