I was looking at Continental's list of general requirements to enter Spain, and I just wanted to double check with everyone here that they are right. They say that a US citizen can go for 90 days without a visa, but some form of proof of adequate funds for the trip, something showing a planned departure, and then it mentioned a Letter of Invitation. All the others I've seen mentioned elsewhere, but the Letter of Invitation when I looked it up mainly comes up with links about the US and visas. It isn't necessary right? Hopefully you guys can help me with this. I leave in two days for a week in Madrid and I'm sooo excited. Thanks.
