Already did my 3 last wkend for 10k CO miles. @ have posted already with notation to Continental for miles.^ I don't think you have worry too much about rates if you just click on "best prevailing rate" in the rate box it seems to match or beat internest,AAA,AARP rates. If you sign up for emails they''l send you out last minute specials acround country w/rates. Only way it can be cheaper I think is if property/ies you are thinking about allow 14-day pre-paid advance.
