There are so many votes for so many places I have loved visiting.
NYC - had such a positive vibe. When I have my gap year (aka my midlife crisis and likely to last more than a year!), I'd love to live there for a few months.
Paris - I've been twice in the last year and had the most fantastic time. Had been a little apprehensive beforehand but loved every minute.
The shipwreck on Zante - yes, very overcrowded but all online reviews I read said this was the case so we found a tour company that have a low maximum passenger capacity and departed early in the morning so we were on one of the first boats to arrive.
Singapore - there are some really magnificent sights to see. Yes, very hot and humid but you're never very far from We were only there for three days on the way to Australia so maybe would have felt differently if it had been the main destination.
Sydney - not quite as expected but we were far from disappointed. It might have helped that we were based in manly and caught the ferry over most days.
Blue mountains - One of the highlights of our trip to oz - breathtaking scenery and snow in the middle of August was a very unusual experience for ds on his birthday!!
I can't think of any places that have truly disappointed. There are several that I have no desire to return to but there've always been enough good points to make it an enjoyable/memorable trip. These include Zante, Ibiza, Sri Lanka, Las Vegas. Ds has been my main travel companion for the last few years but at nearly 17, I think he's had enough of holidaying with his mum so this year the most I'll get away with is a long weekend camping in padstow!!
