If you're trying to get mistletoe from the winter revelers to complete "Bros Before Ho Ho Hos", the following little macro from a wowhead commenter may be useful in cutting down the amount of time you spend waiting in inns and kissing npcs:

/targetlasttarget
/kiss

Target one winter reveler, then the second one, then use the macro. You'll get two rewards and two debuffs.
