We booked our vacation to Las Vegas eons ago - got a rate of $535 for airfare for 2 SEA/LAS, 3 nights at Excalibur, and airport transfers. We booked in May.
This is close to the price I paid last year for 2 nights at Ballys, with only 5 days notice.
I am happy with the price. DH and I should have a blast! We are going to celebrate our 15th wedding anniversary (actually Jan 3rd, but it is easier to go near the middle of the month, not to mention cheaper).
We will be there Jan 17, 18, 19. We are not huge gamblers, and I look forward to exploring the Excallibur!
