Lots here I would not visit again for one reason or another just a few below that stick out
New York was there for the US open, really did not like it at all for many of the same reasons as others
Malta (1986) horrible hotel, rude staff, filthy coastline, overpriced food surly staff in almost every place we went to eat.
San Francisco, (1991) the homeless and begging then was shocking, filthy
Vegas, first visit quite fun over 30 years ago, but second visit we were almost car jacked.
Bali, made the mistake a few years ago of going to Kuta...oh dear, went back about 5 years ago stayed elsewhere, had a great time getting out and about.
I am lucky to have travelled quite a lot and yes some places are just a bit ok and you have to go with the flow but would never visit again, been seen done kind of thing, but visiting New Zealand was not a good trip. Yes some highlights, but also plenty of disappointment's esp the food, we expected seafood, very disappointed, accommodation with lists of dos and donts (shower no longer than 4 mins, dont move ironing board from this position, dont cook strong smelling food and so on) some areas had a bit of a edgy vibe, to many 'Once in a lifetime' 'never to be repeated' rip off prices, and to be honest did not find on the whole people to be welcoming or friendly in the service side of things. 6 weeks around we were quite happy to leave.
