Brian/Justin/Gus Christmas fic
Couldn't find this particular story in the tags:
It's post-513, Brian, Justin and Gus spend christmas together. The weather is really bad, they can't go home, meet on an airport and spend the holidays in a hotel. They have a wonderful time and thing it's the best christmas ever. But all their friends think it was the worst christmas ever. (I think Michael, Ben, Debbie ... tried to get to Canada by car and the car broke down and in Canada Linds and Mel had a power outage.)
EDIT: Found! It's The Worst (?) Christmas Ever by Wren. Link's in the comments.
