I understand that there are a lot of questions about traveling with someone you have not traveled with before or in this case with in years/decades. And I have read some of the other posts on that topic,
To me and to my point with this topic I am more concerned with how much planing you can do then set on the shelf then pull the plans off the shelf and execute them in short order.
Normally there is momentum and a logical progression in my planing with everything being figured out about the time I expect to get the best deals on flights or whatever is the deciding factor in my pulling the trigger. Then within a couple days of buying the tickets I have all the reservations made.
This is plan up to a given point, wait for months or years or whatever then pull the plan dust it off and execute it in what may be a rush (depending on how the timing works) I don’t usually travel like that.
I have packed a bag and been at the airport 2 hours after I found out I needed to go somewhere but that was simple domestic travel and the company footed the bill. This is a complicated 2 or three week trip probably hitting three counties and 5 locations or so.
So how much CAN you plan ahead and how do you pull off a trip with only a few weeks or months notice vs my typical year or so of thinking about it then detailed planing. Heck I usually spend a month or more adjusting the schedule with a spreadsheet to figure out how. Ugh time I need where and what dies that do the the budget (an addition night in Paris is more then an additional night in some small in out in the middle of nowhere.
As for basic expenses... It is mostly a pay for yourself with my sister probably picking up the travel expenses as she has more status and points and what have you and as a bit of a gift as I will (at least on the first trip) be playing tour guide and planner as we cover some places I have been before but that she wants to see.
The trip will be odd in that I figure to keep it fast pace but flexible enough that we can skip some stuff if we just want a did to hide under the pillow. The fast pace is in part to act as a distraction. And while I enjoy sitting somewhere taking in the view of a building or scenery sometimes for hours ideal time is not “distracting”.
This trip may be planned as a Christmas trip. As the idea of Christmas alone just sucks. If that is the case then it is fly into Germany hit a market or two. And a few other winter friendly options, then a short stay in Paris then on to London. Mostly to see them at Christmas time. But to give my sister a chance to hit some of the bigger attractions. (She has been to Paris for a short trip so not much time in Paris,
We have a place to stay with folks she knows in England for Christmas itself (and before/after.
But I may put together two trip planes one for spring /summer and one for Christmas as these are kind of contingency planning. Heck I may plan for just myself to go as an option.
For now this is mostly a thought exercise but I do want to be able to use them if we/I choose. But we have so many variables that our out of our control that nothing can be set in stone. And for someone like me that is extremely at odds with my usual methods.
