December is brutal this year. I booked back in Feb and its only gotten worse so far. I do note that alot of the companies do not even have coupons or promos extended out that far yet, so it will get better, no doubt. I'd book something now that you can live with [i.e. best you can do] and just keep working it as we get closer. I can't imagine the cars stay this high, as reports of prices diving just before the time period can be found after recent renters had lamented the prices even a couple of months ago.....
