Luggage tipp: Have exactly one, easy to grab main piece at luggage that goes on your back or on wheels. Have at most one tiny extra piece to carry. The second your luggage exceeds three it becomes a massive hassle: You cannot hold on to things, you will lose one piece and your fun trip descends into a disorganized mess.

Luggage which clips together like a storage/day backpack combo is very valuable for this: Your backpack might be comically large, but you can haul all your stuff with free hands. At your accomodation, you can leave the large bag and continue on your day pack.

Free hands are critical when travelling by train or bus, or if you just wanna get a snack and drink.

Get a 45 liter backpack with one single massive compartment.

I love this one https://www.peakdesign.com/products/travel-backpack?Size=45L...

And then get a duffle bag carry-on.

This lets you maximize storage on the cheap “1x carry-on, 1x personal item” plane tickets. No checked luggage; the 45L backpack just goes under the seat in front of you.

Osprey also makes a good one. Sometimes I need to check something bigger especially if I have a long walk planned but I usually use an Osprey Porter 40Lish (may be a newer line I haven't tried). Yep. Big compartment and use some organizing cubes/bags.
