My wife and I are 70 and though we've travelled before pre-covid, those were all planned or Cruises. This next trip will be on our own probably in late March through late April. We're pretty active but frankly I have some concerns and need some reassurance. Specifcially, I'm using a mixture of airbnb and booking.com to look up places to stay as RS recommends. After some initial research, I think taking the train through the different cities mentioned above, plus maybe a night in Brussels on the way to Paris, and buying "point to point" tickets would be best. And after a stay of 4-5 nights in London, we plan to rent a car to explore the English countryside and maybe Wales, before returning to London and flying home.
I'm really just looking for someone who's done this kind of multi-city trip to "hold my hand" and reassure me about this and to provide some tips and /or caveats since this will be, despite our previous organized trips, a totally new experience. I'm aware too, that we need to make air and lodging reservations very soon, and possible trains as well. Thanks so much!
