I am not saying that you can not find deals online. I sure hope you can, but know what you are doing and if your gut tells you something is wrong, repect it!
A news snippet from the Kim Komando Show "Scammers are increasingly taking advantage of vacationers. The scammers are offering fake vacation packages and holiday homes online. Few travelers check the scammers' credentials and lose their money. Digital scams are getting harder to detect."
Suggestion? If you have a local travel agent, they will probably be glad to compete with these offers and will offer security in getting the the REAL DEAL. I do not want to let someone I have never met set up my family's vacation for several reasons. The success of the vacation, my family's safety and the fact that someone I do not know is aware that we will be away from home, where and how long. What an invitation to clean your house for you?
A quick disclaimer, I am not involved in the travel industry and I am not recommending anyone in particular. Komando's article just struck a note of concern for our neighbors.
