You do not have to return to the counter to use L & M, when you return. You park your car in any available space and go to the booth at the end of the row of cars. Someone will be sitting in there and will print your receipt - took maybe 5 minutes. I highly recommend them. I was skeptical at first, but when they saw me walking over to Dollar with ressie in hand, they called me over and beat their rate. Basically, gave me extra driver for free. Cars were all new, very clean, no problems at all. Very friendly staff too.
