There is the unmistakable feel of fall in the air—the leaves are starting to change and the air has that crisp hint of winter, but that doesn’t mean it’s too late to book that last end of summer vacation. Expedia is offering some great deals on hotels in the last big sale of the season. Book by September 30 and travel by October 20 and you could get 50% off rooms in some of the hottest destinations. Air + 4 nights in the Plaza Hotel and Casino in Las Vegas is going for as little as $272 per person. If you’d rather head to the beach to work on that tan before winter truly arrives, Expedia is also offering deals to Mexico, such as air + 4 nights at the Great Parnassus Resort and Spa All Inclusive Resort in Cancun for only $674 per person. With these kinds of savings, now is the perfect time to squeeze in one last trip before the holiday season is upon us.
