From what I've heard they both read the same way. So a Finn could read a Hawaiian text and they would understand even if the Finn wouldn't. And vice versa (even though Finnish has more letters).
Same here, I reckon Monaco / Cannes would be fair type-inns. Possibly add Malmö for Copenhagen as well, even though the latter is the more popular one. Good quiz tho!
I only got the average score, but I did manage to get Catania. I couldn't remember the capital of Sicily, so I tried it on the off chance that it would work, and it did!
