List of tasks:
1) Cancel stuff - newspapers, garbage service - done
2) Credit cards - chip card? Notified bank about destinations? Here's an important point - notifications run out after 30 days and you need to re-notify - I did all mine by phone that way they can do the whole 90 days and all 10+ countries
3) Copies of all documents on a device - done
4) Taking a small computer? I always do. Make a plan about storing cords and such - never travel without one plus a phone - I did pick up a very nice cord organizer
5) The most difficult part of a trip is the route from the hotel to the train/airport. Get the first route planned. After that, I usually find it easy to get around. - I think you mean airport to hotel? With the cat & and an extra bag we are splurging on a cab fro CDG
6) If you plan on going to a theatre/opera in some cities, make reservations now. Some places sell out. - done
7) Do you know anyone in those cities? Make plans to visit. - done
8) Can you write the trip off as a business expense? Visiting some business may allow some parts of the trip to be written off. - The good news is yes!
9) We have learned that storing each day's reciepts in separate bags is a good idea. Much simpler. Take a bunch of small plastic bags. - good idea
10) Will you take pictures? you can't store 90 days of pictures on a device. How will you store pictures? My days of taking hundreds of photos are over - I have ample storage on a few SD cards
11) Stop mail. Note: The post office will only store mail for 30 days - BOOOO. What will you do then? Fortunately I live in a very small town - no problem on a 90 day mail hold. I do 99% of everything online so we receive very little mail.
13) Go to the Rick Steves section about audio guides and download some of these. Note: They take a lot of space - great idea
14) Do you have an UNLOCKED phone? We did not. It would have really helped to have one. We would have paid to do that before the trip. If your phone is unlocked, you can get SIM cards and use it in other countries. Another approach is to find map apps which don't require telephone service. Yes - unlocked phoone all set - will buy sim on arrival - plus my phone will still have Verizon service if needed.
15) Make a plan for the last morning. Throw out all food from the refrig. The freezer is a danger zone - if you lose power, this could be quite dreadful - rotting food? Clean that frig!! Turn off the water at the house water shutoff. Get timers for lights. Turn off the air conditioning. Empty the trash. Dump the used baking soda down the sink. - Yes - we live full time in a 40' motor home - very special needs for leaving.
Almost all trips are shorter than a month. Thus, longer trips have some special rules. We were in Europe for 40 days, and ran into the problem with the bank card - we lost access for a morning due to the 30 day limit. The mail stop is only 30 days. What will you do then?
Nice list - thanks
