If you enjoy walking as a way of seeing a new destination thrn pack comfortable shoes. And a spare pair. I'm size 13uk and in some countries it's impossible to get that size especially at short notice.
I love my Kobo Libra 2 ereader. I can buy books directly from Kobo, sideload my existing ones. Borrow books from my local library from the device and read saved articles in Pocket on the device. Battery life is great and it's usb c! Love it
