When do you leave and do you know where you are going? As I recall in Italy a bar (liquor - not coffee) has to let you use their bathroom for free. Otherwise, just buy something (water, etc.) and they will let you use it. I don't remember seeing one in the grocery stores but that doesn't mean that it wasn't there. I'll try to find my guide book that says what the law is over there. All train stations I was at had a bathroom - but like seconder said, you may have to pay to use them.
I was just in Scotland and didn't have any problems but I was based out of a home. I actually was pleasantly surprised at how well my uc behaved while I was on vacation. It must have been the lack of stress and all the sleep I got. I had more trouble with not feeling good when I had to get up early for a couple of things we did but it just bothered my stomach and didn't turn into any D problems. I hiked, took long train rides, shopped for an afternoon and had no urgency issues. I remember having the same thing occur prior to diagnosis last year when I was in Italy. Just being on vacation helped improve my symptoms! I did a 2.5 hour hike with no need for a bathroom! I hope that you get to have the same UC experience that I did. It was nice to not have to worry too much about where the closest bathroom was. Enjoy your trip!!
