Hi Matt! Good luck on the move. I have lived in Cancun for a little more than 5 years. It's certainly not always easy to live here....especially if you have a hard time finding work. I planned my big move for several months and made several trips to Cancun before the big day. I wrote the story of how I ended up in Cancun and talked about the move a bit on The Cancun Blog. You can read that for a little insight on making the transition. You can email me any particular questions you might have, as well.
Go to http://www.cancunblog.info and do a search for Susan's Story. You'll find about 9 chapters, I think. Enjoy!
