Honestly, I try not to think about it. We go once every two years. So when my year countdown begins in February, I start researching and read as much as I can. Then 6 months away, I start planning full force. I have so many notes, spreadsheets, lists, etc on my computer (it’s my happy place) and I update and tidy things up. I also use a binder and print out charts, lists, etc.
