Yes, I am a fan of European travel. Trouble is, for me and many others, it's much more complicated as we get older and as the world has changed.
When I planned my trip in 1987, it was a solo venture. I traveled around the continent without reservations. When I visited England, a bit of Scotland, the Czech Republic and Germany once again, I had some reservations, but not everywhere. It's trickier with four travelers. For whatever reason, for our trip this month I booked three legs of our train travel with few problems. If I were superstitious, I would say someone or something does not want us to take a train from Wurzburg to Mainz. I have tried to book it seven times now, on the website and on the Deutsche Bahn app. I've tried with different credit cards. No go. Hotels, too, are more difficult with four. I didn't get very far with the suggestion that we consider a youth hostel or two. Somebody, I won't say who, is a bit hostile to hostels.
