I always try to enjoy every place I visit and a lot of the places listed so far that I have been to, I enjoyed them. Vegas, LA, San Francisco (admittedly like 15 years ago), new York, Dubai, France, Malaysia, Cancun.
The only holiday I didn't enjoy was doing a driving holiday through some of America's inland states. My husband wanted to visit all the states and these were some of the ones left he hadn't visited. Pittsburgh, Maryland, Illinois, st Louis. Forgotten the rest.... bloody boring! Nothing in them that was interesting. Everything was boxy roads and most states looked the same. Highlight of the trip was Washington and Virginia.
