I won an all expenses paid real singles tour. Is this legit?

So, Iíve really been getting my hands deep into the whole online dating thing and Iíve really taken a liking to foreign women. A few weeks after I signed up for an account in one of the sites I normally browse through, I got an email from a foreign marriage agency stating that I won an ďall expenses paidĒ real singles tour. My question now is, should I actually participate? Is this thing legit? I donít wanna end up in some foreign country because of some elaborate scam. To anyone who has ever joined something similar, Iíd really appreciate any advice or insights you can give me.
