Priceline.com is putting more than 50 of the summer's most popular vacation destinations on sale. From now through June 19, 2005, customers who purchase a specially designated priceline vacation package will receive an instant rebate of $25 per person, up to a maximum of $200.

On-sale destinations include Las Vegas, Orlando, New York City, Miami, Cancun, Cabo San Lucas, Boston, Albuquerque, Amsterdam, Denver, Jamaica, Madrid, Puerto Vallarta, San Diego, San Francisco, St. Maarten, Venice, New Orleans, Munich, Scottsdale and Washington, DC. To qualify for the rebate, customers must book a minimum 3-night stay for at least two adults. Travel must be completed by September 6, 2005. Rebates apply only to select hotels. Prices and availability are always subject to change.

The rebates are even more compelling because they're on top of priceline.com's already discounted vacation package prices. Typically, customers who buy a priceline.com vacation package save up to $200 over the price they'd pay if they booked their hotel and airfare separately. So total savings, depending on the selected package and number of travelers, could be as much as $400.

Here are some examples of sale packages that were available as of May 25, 2005 for travel between June 2 and September 2, 2005. Quoted prices are per person based on double occupancy and include round-trip airfare and hotel accommodations. Prices include taxes and fees, and include the $25/person rebate.
