I am able to book any available Grand Gatheriing experiences for our December trip tomorrow. I know I should be on the phone a little before 7:00 am. Do I just give them my trip dates and ask for anything available for those dates?? Or will I need specific dates.. I want Epcot Illuminations/ Grand Gatherings for Dec 18th etc... I basically will take anything available on any of our days there. We are a group of 8. Not too picky but just want to experience some of the neat things they offer for the Grand Gatherings. Thanks so much for the help!
