Someone forwarded this article to me from msnbc.com yesterday.  We have been advising our couples for years to tell their guests about the dangers of booking their trips on sites like this.  Unfortunately we have seen countless situations where guests think they are getting a great deal, are "walked" to another hotel, and they are separated from the rest of the wedding party. 

When you are planning a Destination Wedding it is very important to make sure that you are working with a specialist that has lots of experience with DWs, uses reliable travel suppliers, and has the relationship with these suppliers to address any issues that may arise.  This shouldn't happen to any guests, it ruins the trip for the guest and puts extra stress on the bride when she should be enjoying her big day.  Hotels, like airlines, overbook all the time because they are anticipating "no-shows" or cancellations.  When a hotel has to "walk" a guest they usually start with guests that booked with these types of cheap internet sites.  Book with caution!

Jack Taras and his friends thought they would be checking in to the Occidental Grand hotel on the Dominican Republic's postcard-perfect Eastern shore for Spring Break. But when Taras, a 19-year-old sophomore from Providence College, arrived at the resort, he was greeted with the hotel industry's latest trick: he was walked down.

"They were sent to hotel that wasn't as nice," says his father, John Taras. He phoned his son's online travel agency, Cheaptickets.com, and asked about the downgrade, which lasted the full five nights of Jack's stay. It deferred to the hotel, which offered an apology and a vague explanation of a "computer mishap" that resulted in an overbooking.

"Walking" is a practice that's as old as the hotel industry. When a resort is overbooked, it typically sends a guest to a comparable property, covering the cost of transportation, a phone call and accommodations. But somewhere along the way - probably at the start of the current recession - the word "comparable" was conveniently dropped, and hotels quietly began sending guests to lesser properties.
