Time to test pack to see if everything is there. It's so much more fun. I start a week or so in advance of a trip laying out everything that I intend to take on a spare bed. Then I check it all over frequently. It's amazing how much I can decide to leave behind or other things I really need.
Time works wonders on the memory.
Try to get everything into 2 bags. I use wheels for my 2 nd bag. If Dean at Four Seasons Travel is getting your tickets and passes and for some reason they don't reach you at least a week before departure, call him at 800 331-3136. He never has failed to get tickets out on time, but there could be a first time. It all helps.
