When is the best time to book a Las Vegas vacation? We went in January and only booked 5 days in advance (through travelocity.com). And we plan on going next January (2011) again. Is it best to book last minute, or how far in advance should I plan and book? It seems to me like the prices I am getting now are similar to the price I paid with only a few days notice. I have signed up to get hot travel deals from Alaska Airlines in case there is a sale (we leave from SEA), so just in case we get an amazing deal in the email we can jump on it. Thanks!
