POSSIBLE TRAVEL PLANS FOR 2016

The toughest decision in my life right now... Any suggestions would be helpful!
  1. Quit my job, go for a 3 month holiday and hope I find a new job quickly
  2. Ask for half pay for 2 months and do northern and Eastern Europe
  3. Take 3-4 weeks off and just do Northern Europe
  4. 2 week trip to Vietnam or nothing in 2016 and do a big trip in 2017
