Lot's of complaints there. Would not do any business with them.

Nature of Business
This company offers vacation travel packages by means of unsolicited facsimile or Internet pop up advertising to Cancun, Orlando and Daytona Beach among other vacation areas for a cost of $299 per person. This price does not include the cost of travel to and from your destination, taxes and transfer fees, and all other costs associated with a vacation. The Bureau suggests you ascertain the name of the resort where you will be staying and then contact them to verify your reservations prior to making any non-cancellable travel plans. You may wish to check with your local travel agent to see what is available locally and at what price before agreeing to accept this offer and paying any money. The sending of unsolicited advertising by means of telephone facsimile machines is contrary to both Federal and Florida Statutes. Specifically, U.S. C. 227 and Florida Statute 365.1657. If you object to receiving this type of solicitation you may wish to file a complaint with both this Better Business Bureau and the Florida Division of Seller of Travel, 2005 Apalachee Parkway, Tallahassee, FL 32399-6500 (850) 410-3805.

When I tried to pull up the website I was given the next day, I was re-routed to a "rip off" website, but when I telephoned the company, I did speak with the same rep who said they were redoing the website and gave me another website.  It did not have much of the resort information on the site, and when I called, I was told it would take several days.     I already gave them credit card information.  I did get the package in the mailk delivered DHL Express as they stated.  Can I expect them to follow through with the vacation plans?

Supposedly Cancun Best Fares.  Package delivered said IRR out of Orlando Florida.

That's just one of the names that they are using. Its a list. If you make the trip let me know. I will respond to you. I am suppose to leave in May 5th 08.
