Hotels
Dropping from first place in August, Santa Fe, N.M., rounds out the top five with a five percent decrease. The news of the fires that hit a couple months ago continues to have an effect on demand in the area and hotels are now dropping rates even further to keep rooms filled.

Rochester, N.Y. took the top spot with a 13 percent drop at a Hotwire.com average of $81 per night.

Air
This month, several alternative air hubs to major destinations make the list. Coming in at first place with an 8 percent decrease is Arizona's second largest city, Tucson. Three cities are tied for second place this month with a 4 percent decrease each, including Burbank, Calif., Oakland, Calif., and Hawaii's Big Island, which appeared on the August list as well.

Following closely behind with a 3 percent decrease is Vancouver, B.C., which rounds out this month's top five.
