Yep its on every year. They have Whooville carol singers and a performance with the Grinch. They had snow amd bubbles floating to look like snow. To be honest I thought that the whole park looked fantastic especially Seuss Landing with the wobbly christmas tree.
It was a complete Grinch overload but in a good way. You'll love and make sure you see it in the afternoon as when the sunlight starts to fade it looks magical.
