Question

how long can an american stay on vacation in spain?

Answer 1

Yeah, I've been hearing three months.  

I only stayed for one, so when I checked, they said I was well within the rules, and that was all.

Answer 2

American Citizens do not need a visa when they travel to Spain for business or for personal travel. The stay in the Schengen area should not exceed 90 days in a 6 month period. Please note that the American visitor will need to present a valid American passport (valid three months beyond intended stay), proof of sufficient funds and a return airline ticket.
