Some college students are suing a Long Island travel agency that canceled what was supposed to be an "Xtreme" spring break trip to Mexico and did not refund them.

College sophomore Zachary Snitofsky, of Dix Hills, wanted to spend his spring break partying. And the videos on the Xtreme Trips website, from trips in Puerto Vallarta, Mexico, were exactly the vacation he wanted to take.

Snitofsky got more than a dozen friends to sign up, spending thousands of dollars. But when the travel company wouldn't give details about hotels, flights or any other information before the trip, some friends backed out.

Snitofsky says he began speaking with the company and the situation seemed sketchy. He says Xtreme then canceled the trip but continued to charge their credit cards thousands of dollars. The company website says it has a no-refund policy.

Attorney Peter S. Thomas calls it "a classic type of scam." He's representing a growing list of college students from Long Island, Westchester County and elsewhere in the U.S. who never got a vacation from Xtreme Trips.

According to its website, Xtreme Trips is based in an office in Plainview. However, it's not there anymore. The current tenant says Xtreme moved out last month.

Thomas says the company is now based out of the home of company head Mark Tobin. No one answered the door at his Huntington home. Calls and emails to another company official were not returned.

When booking a vacation, travel experts say to always read the contracts and online reviews for travel agents. They also recommend purchasing travel insurance that covers cancellations.
