Good guitar to practice with while I travel?

Through September, my family and I are exploring the UK (my first time travelling outside of Australia)! I’ve been trying to practice more consistently this year, and I’m worried this will not only bring me back a notch, but also drive me crazy since I also regulate by noodling.

The trip is quite expensive so I’m very focussed on affordability, and I’m not performing so I don’t care how it sounds, only that it’s not difficult to play (and preferably not too loud). Any there any suggestions of good, cheap, sturdy and compact acoustic guitars that would be easy to travel with would be much appreciated!!
