We could vacation in Alaska during Christmas, but I feel a more desirable climate would be better for the children.

desirable

they are all desirable but the SS is the most desirable

A white Christmas is highly desirable, but snowfall in Ireland is relatively light, so a snow-filled holiday doesn't always happen. Christmas day is a time for families, so gatherings are often quite large. Dinner is generally served early in the afternoon instead of later at night. :) :)
