I had seen mention of this somewhere else, but thought I'd relay my personal experience. They did offer sugar free hot chocolate and sugar free cookies at Mickey's Very Merry Christmas Party. The sugar free hot chocolate was mixed up fresh when you requested it, so it was very hot. They also offered apple slices as an alternative to the cookies.

Regular hot chocolate stands (such as at Osborne Lights) did not have sugar free hot chocolate available.

Just passing this along so that maybe it can help next year...
