Bah! Winterfestday just arrived in my game and it's one day too early! The new stuff isn't patched in until tomorrow. :(
@LadyKyn, What I do for the Grand Meal is give the leftovers away as a gift to some npc sim that I invited over....that way my sims won't be eating it and getting fat in the days after the holiday (can't take credit for the idea...it's what my step-mom does IRL ....I'm the one usually taking a crate of food home, hahaha)
I edited the holidays to add a WinterFest Eve, and moved Father Winter's arrival to that holiday (as well as give gifts, attend holiday ceremony, baking and decorating traditions). Then on WinterFest day we do Decorate, Open Gifts, Festive Spirit, Holiday Lighting and Grand Meal. I always invite family of my active household over for the grand meal, and then send the food home with some of the guests.
