I know airfares tend to be best-priced 2-3 months prior to travel - does anyone know when I should start really shopping (i.e., checking prices daily or every other day) for a rental car? If I can get the cost down (on an 8 day rental, econobox) to about $150 including the myriad taxes and fees, I'd rather do that than the towncar. (I typically plan dinners at resorts, and refuse to take the roundabout bus routes, so I spend a fortune on taxis.)
