TULSA, Okla. -- Alamo Rent A Car has launched the "Alamo.com Family Vacation Sweepstakes," promoting its best-rate guarantee for reservations made online at Alamo.com. Consumers can enter to win one of 300 trips to Walt Disney World Resort or Disneyland Resort online at Alamo.com. They can also earn four additional entries with each qualified Alamo rental from Feb. 7 through Apr. 30.

John MacDonald, vice president of marketing for Alamo, said the company is backing its best-rate guarantee with an additional 10% discount, should a customer find a lower Alamo rate for the same pickup location, reservation dates, times and car type.

Each of the 300 packages is for four people, and includes airfare, Disney theme park passes, an Alamo rental car and hotel accommodations at a Walt Disney World Resort hotel or Disneyland Resort hotel for five days and four nights. Trips will be given away at the rate of 100 per month. Those who have already entered are automatically entered into the next month's drawing. Customers can improve their chances of winning by continuing to earn additional entries with each qualified rental.
