Came back yesterday from Croatia and was down south between Split and Dubrovnik on a campsite.
Staff said 60% of holiday makers were German this year which was way higher than normal, most seem to have driven rather than flying by range of cars / RVs etc, Italians normally make up 30% but there were not many of them across the season, Poles / Czechs / Slovaks / Slovenians tended to make up the majority of the rest. Last weekend was great rush back and spoke to one family who had family members drive back earlier with a 28 hr trip back to Bavaria due to Covid / tunnel checks, they left Thursday and has a 12 hr trip. Site manager said normally airport shuttle runs daily but this year rarely as most felt safer driving.
Talked to quite a few Germans and many seems to have diverted from France / Spain this year due to Covid. Course it was a very small sample so who knows.
