YYZ would be our starting point. Destination would FKK and 2 stopovers on the way (ZRH and SPU). We have a whole list of places we’d like to do layovers at only if feasible (LIS, PRG, HEL, BUD, WAW, LUX, OSL, HKG, TSA). It’s a longer list but these are the ones with more interest.

We would be doing everything together except FKK. I would stay there 5-7 days and my wife 3/4 weeks.
