Vacation choice: XP1 or Leica M6

This is probably not the best place to get an unbiased range of reactions for my question, but I'm curious what you all would prefer taking on a long vacation: The XP1 or a Leica m6 with a 35mm cron (or something similar based on your experience). The basic dilemma obviously is the convenience of digital vs. shooting style of film but also that the Leica with good glass is just amazing. Of course if anyone has any experience with the M adaptor I'd love to hear. Also I wouldn't take both, because that's just a pain.
