Just got back from Antalya. Lovely place but all British at the airport said the same thing - Russians and Germans are rude c*nts. Also some Turkish shopkeepers are very sly and will try lots of tricks to get money out of you. If I did go back I'd stay at a resort, much more relaxed. Personally think Oludeniz is way better and more beautiful.
I've come across Russians in Cuba and they were indeed generally really rude and cold. On the other hand, everywhere I've been the Germans have been fantastic. Sardinia this September was mostly German tourists and, again, they were superb. Beautifully mannered, friendly and cultured. We had a group of around eight German girls staying in our hotel and they were lovely. In sharp contrast to the way gangs of English girls act abroad. The tourists we like to avoid abroad the most are the English and Americans. We've encountered Americans in Iceland, Mexico, Cozumel and Barbados and they have always been absolutely horrific. Mind you, this year was my first time on Italian soil and I was concerned beforehand. We had previously stayed on the Spanish island of Formentera, and although it is just south of Ibiza it is a place mostly populated by Italian tourists. So much so, that the locals in the tourist industry tend to speak Spanish and Italian whereas in Ibiza it will be Spanish and English. Anyway, the Italians in Formentera were horrendous. Loud, very rude and laughably pretentious. Thankfully, the Sardinians were absolutely wonderful and nothing like their mainland cousins.
Regarding Turkey, I'm with you on Olu deniz. We loved it there and it's beautiful. Like with any tourist place though, you need to be aware of people trying to get extra money out of you. I remember looking for a big Turkish flag in Olu Deniz but could only find small ones. This local seller said he could get me one but was looking for the equivalent of around £70 for one. I politely declined. A day or so later we got the bus to Fethiye and I came across a shop that sells boating equipment and, of course, they stocked flags. I bought a massive Turkish one for around £17 Sterling. That night back in Olu Deniz we came across the guy who was going to get one for me and I told him I'd manage to get one in Fethiye. He asked how much for, and when I told him his face was a picture.
He clearly realised we'd clocked as as trying to scam us. He said no more. Many people in tourist spots across the world just see tourists as walking wallets.
Anyway, the picture below is our snorkelling spot in Sardinia in september.
