There are always "Elf," which, in the past, has had two North American companies (east and west) doing a 6-week tour around the holidays, and a zillion productions of "A Christmas Carol." Also, we now have "A Christmas Story," which has become a classic already.
As for other holidays, JCS is about Easter, but isn't viewed that way. The Stephen Spielberg animated musical, "An American Tale," opens with the family celebrating Hanukkah. I'd love to see it done as a stage musical. (If it were Disney, I'll bet it would have been produced already).
The Burl Ives "Rudolph the Rednosed Reindeer," the old TV special, would make an adorable stage musical.
Audrey, the Phantom Phanatic, who nonetheless would rather be Jean Valjean, who knew how to make lemonade out of lemons.
