Favourites UK: Southwold, Suffolk coast. Happy family holidays as a kiddie. Went back last summer and was relieved to find it's still lovely. Pity my car decided to spew the contents of its radiator all over the carpark for the second time this summer.
Big shout for Northumberland. I could tell you about lots of other lovely places in the north-east, but I don't want lots of "foreigners" cluttering up God's chosen land. Teesside is there for a good reason. Southerners see it and turn back, thus leaving us in peace. Can't believe even a Celtic fan would consider it for a holiday
Fave worldwide: you lot probably know about my enthusiasm for Russia by now, though a lot of it could be placed under worst destinations as well. Especially if you like taps that consistently deliver water. But for the chance to see a culture both alien and recognisable at the same time it's fascinating; for the sense of history in a town like Suzdal it's unbeatable; for the vast tracts of untouched countryside there's nowhere close.
Iceland gets an honourable mention at this point. Two skidoos and a lump of ice the size of North Yorkshire. Good hangover cure! Venice is the most beautiful city I've seen, but it's like a museum rather than a place. The city I'd be most able to live in is probably Copenhagen.
Least fave, UK: can't stand Birmingham, but that's not really a holiday destination. Was disappointed last time I was in Edinburgh, but loved it when I was younger (and it was summer, and not freezing cold, and the festival was on). Didn't much like living in Devon, but enjoy Dartmoor for a visit. Don't have much time for the Welsh (Cardiff is the only city where I've been offered violence in a pub, largely due to having an English accent. Given the choice, I moved to Glasgow and had no trouble with the same accent proving that Scots are generally OK), but haven't seen enough of the "country" to judge its merits as a destination. Reporting on a football team means I've seen most of the towns you'd never want to go near. Perversely I quite like Rotherham, Manchester does nothing for me, Wolverhampton has no discernable reason to exist.
Least fave worldwide: Australia has no appeal for me, neither does the Gulf or much of SE Asia (irrespective of recent events). NZ could tempt me, but it seems like a long way to go and see a recreation of Scandinavia!
As for places I've actually _been_ Milan was a big disappointment. Dirty, ugly and alarmingly bereft of style. And the Duomo was covered in scaffolding. High-tailed to Lake Como and found the villa I will buy when I win the lottery. Didn't warm to Amsterdam, either. Might have been the uneasy sense that I was sharing a city with every Aussie backpacker in the known universe.
Paris was fairly neutral, though I was very young when I last visited. Aix-en-Provence was a disappointment (worse attitude than Paris!) but Marseilles was fun. Nice average, Monaco hilarious (girlfriend proved annoying on that trip, prompting an impressive bust-up on our return to Stansted!).
Ask me in the autumn and I'll tell you about Siberia, Mongolia and Beijing! Hopefully.
