Folding tires

Pacneil, thanks for summarizing the good reasons I also use only folding tires. And, so easy to pack.  You can even carry one in a jersey pocket if you want, and are super easy to pack in panniers or a trailer.

I'm one of those who has given up on carrying a spare. I carry a Park Tool tire boot. They have an adhesive surface presumably so you don't have to worry about it sliding off the hole. The only time I ever used one was on a club ride when another rider with super light 23 tires had a blow out. It got him home about 10 miles. You may find you have to ride with slightly lower tire pressure to avoid feeling a bump but most of us tourists aren't riding on 120 psi so that's probably not an issue
