Best to do, IMO, is grab a rate today, whatever seems best, keep checking till time to go, most often rates drop a lot as time gets closer. I have a National rate for $134, full size, for 8 days next week that started out over $300 some months back. I had a $115 Alamo rate, mini SUV, for the same, though just cancelled as the National came down so much and actually is a better car for me. Keep working on it.
