Tell me about your Travelers Notebook....

What I like about them is that they can be anything. I tried using mine for bullet journaling and to-do lists and habit trackers for a while, so planner people could come at it from that angle. At the moment, I scrap small photos and art journal into mine just like any other small scrapbook or art journal, so it works from that angle too.

I haven't had any problems with them falling apart as long as they were stitched. Some of my hand-made stapled booklets pop a staple once I get them a couple of inches thick, but that's really my fault for using too many sheets and trying to add too much heft to individual pages. As long as the ones I make are stitched with a reasonable number of sheets, and I don't use chipboard on every single page, I'm fine.

miominmio is right, just fall down the YouTube/Pinterest rabbit hole and search for what people are doing with them and you'll find something that grabs you. And you can easily make a cover with felt or plastic to test out sizes. I started out with a personal size for bullet journaling and changed to a standard size this month and like it a lot better for the kind of scrapping I've evolved into.
