It feels like Britain because it's at the seaside :)
There's something true in that. Plus the microclimate there means the trees aren't the Polish birches and evergreens etc but more deciduous ones like in England.
I'd love to see the Tatar villages.
They are very worth a visit! I've only been once but would go again. There are restaurants that serve Tatar food.
And aren't most cruise passengers of the wealthy and aged kind?
Cruises are dead right now due to Covid; that won't change soon. Having said that, life aboard a ship has its frustrations but is worth it. I used to work on a ship, an industrial one (the largest in the world, like a floating island), and would go back again right now. And might.
On cruise ships though, the passengers may be able to afford the fare, however very few are high-spenders.
