I've been checking for March 8 - 19 (11 days) for quite some time and prices have been pretty high. I'd say I check almost every day, and just noticed this morning that Alamo has lowered prices for mid-size SUV and full-size car. I was able to use a Sam's coupon for 11 days for a mid-size SUV for $265 total. Not as good as past trips, but definitely the best I've seen since I've been checking since last May - a full 10 months before the trip! The Sam's coupon also includes a free additional driver, and DH has an Alamo membership, and we definitely prefer a company that's at the terminal (like Alamo), so I think we're all set now. Of course, I'll continue to check up to the day before the trip - LOL!
Hope this helps someone else here!
