My wife and I have enjoyed many European trips built using Rick Steves guidebooks - Italy, Paris, Germany, Austria, Scotland, Ireland, etc.. I have been the planner -- planning routes, lodging, auto rentals, etc. I've planned trips for just the two of us and for groups of up to 6-8 friends.
I enjoy the planning but now I'm looking for ideas that could make planning and travel easier. Group trips organized by others are OK but I no longer want to be "in charge".
Background / setup:
My wife and I are in our mid to late 70s. We're healthy. We both enjoy walking, but now for fewer than 10,000 steps per day. We've looked at several Rick Steves tours but have felt that the expected ability to walk 6+ miles per day could be an issue for us. We had scheduled one for Switzerland last year, but other issues caused us to cancel.
Driving has become much less attractive to me. I am a very safe driver, but it has become a stressor to feel safe in unusual situations like European driving - I've become less comfortable with reaction & thinking time while driving at my age.
We always love Rick Steves lodging. The recommendations are spot on and always enjoyed.
Beyond Italy, our other current travel interests are France, Switzerland, and England/UK and Scandinavia and Sicily.
We've enjoyed river cruising (Viking) but lately none caught my interest. These days they are mostly too short (6-7 nights). We have a good wine themed cruise (AmaWaterways) in Eastern France on our tentative schedule, but it's 2+ years away.
So -- my questions --
How can I plan travel within the following constraints?
No driving. Trains, taxis, etc. are fine.
Average walking (not overdone).
Low planning "stress", more like "taken care of"...
Next travel in 2025-2026+
Sorry if this is too long or sketchy. I can answer questions if that will help.
