With you OP. Stonehenge. It's a bit over-rated, and you have to PAY to get close to it, otherwise you're half a mile away. Seven quid each when we went. We just took a few pics with it in the background, spent half hour there, and then went back to Southampton where we were staying.
Also, yeah the Mona Lisa is tiny, and a bit shite.
Statue of Liberty was OK, but a bit over-rated I feel.
Lands End AND John O'Groats. Don't know what I was expecting, but they were both SO underwhelming!
Been to 2 Disneys - Florida and Paris. Found them both over-priced and crowded. We got on 5 rides in about 8 hours - utterly disappointed. Wouldn't go to any of them again.
Didn't think the White House was small. But I am not sure what people were expecting. Were they picturing something the size of Buckingham Palace?
I am also shocked at the Great Barrier Reef and The Grand Canyon being underwhelming. I thought they were both stunning. I also loved the pyramids in Egypt. York Minster is amazing too. Maybe it's all subjective. I HALF agree about Harrods and Hamleys; both huge, but massively over-rated and stupidly expensive and ALWAYS rammed with people!
I have also heard St Petersburg is much better than Moscow too.
And apart from Hamleys and Harrods, I love most places in London - and also New York and Paris impressed me too! I adore Manhattan, and could walk around it for days.
