In theory a Schuko or "contour" plug should be able to fit in an Italian 16-amp socket (thicker pins). Some of them have overlapping holes for 16 and 10 amp plugs.

Ragnar, maybe you should buy one of those cheap-ass travel packs of adapter plugs and when these kiddies need one because they forgot, you offer to rent it for a modest fee. [Linked Image] [Linked Image]
