Seems to be about the same thing about plugs as in Austria. Every supermarket has an aisle with light bulbs, batteries, power strips, plugs and stuff. Bigger stores even carry bulk cable, rewireable extension strips, light sockets,...
You're right that this is he most professional way, so I'll probably take our other (unfused) adaptor and try to get a plug (at the same thing in turin I never got to something like a supermarket. I just kept running around at the EYP venues).
Towel is the easiest way, but takes more time. (Something really precious at EYP sessions).
