Most of my trips to the US are visits rather than holidays per se. It's so easy to pop across the pond for the afternoon/day/weekend because of the time difference and this isn't really possible for other places of a similar flight length.
Other than German my knowledge of languages is limited so it does make for a convenient option in that respect although the language "barrier" doesn't put me off visiting other countries.
The people are friendly and welcoming.
The only problem is the food - even in cities it takes effort to find somewhere decent.
