Car rental prices moving lower
If you're headed to Hawaii later this month (or probably next month) recheck your car rental prices. I've seen them move substantially lower at both OGG and KOA. We're talking under $100 for a full-size car for a week, before the nasty taxes and fees. Dollar/Thrifty seems to quote their best prices if you go directly to their website and DON'T put in any codes, but the competitors all use the code/coupon game (although Alamo generally only seems to have coupons these days -- the codes don't do much).
I'm finding Dollar/Thrifty, Alamo and Budget to have the lowest prices at the moment. Looks like an old-fashioned price war. Bookings must be soft.
This is why I always reserve a car when I book my airline tickets, but always check back periodically for better prices. Sometimes they go up, sometimes down, it's impossible to know.
