Hi, I am looking for a rental car from Monday, Aug. 11 (10:00 am) returning it on Friday Aug. 15 (6:30 pm). I checked out the info on mousesavers.com and found some very good info. However, these are some questions I have. When putting in coupon codes, and the rate doesn't drop from the reg. rate, does this mean that they won't accept that code, or will be be deducted when I check out the car? Another thing, I found that the time I want to rent one is close enough to being a "weekly" rate, over the daily rate. If I put in return date the 16th (which is a Sat.) is a little cheaper, could I actually reserve it for that date, but then just return it a day earlier? Do they frown on that? Thanks for any help you can give me.
