We did this trip in the other direction, Budapest to Amsterdam. We did the leapfrog once. I think the difference is because we went downstream on the Rhine and Main so it was easier to get to the stops rather than "busing ahead".

It is quite durable; I've taken it on at least seven trips. If you line the bottom with a tightly rolled change of clothes to make a base, it stays upright pretty well.

I use this one. Arxus Travel Lightweight Waterproof Foldable Storage Carry Luggage Duffle Tote Bag https://a.co/d/ii5l7cA. Sorry, I don't know how to paste links. It's on Amazon. It is very lightweight and folds into a very small shape. On the other hand, because it is so thin, it doesn't pad anything inside. I usually just use a large purse on the way to a cruise and pack this for the return trip. The purse fits inside for the return trip and there is still a lot of room left.

If you have paid for air plus, you can call the air department directly. I use a travel agent but can call directly. This has changed from 2018. Now, there are times when it is better to have your TA go to bat for you, but you do have a choice of whether to call directly.
