I have a similar question... I was just pricing out a 3-day rental for this coming August out in SLC, and it's looking like it's around $10 cheaper (on a FCAR) to do a 2-day (Saturday-Monday) rental and then a separate 1-day (Monday-Tuesday) rental than it is to do a single reservation (2 days + 1 day). My dad will be an authorized driver (woohoo USAA) and will pretty much be the sole operator of the car after Monday afternoon, but I don't want him to have to bother with going to return it and do paperwork for a new one (nor would I be able to accompany him, even though the reservation would be in my name...).

Is there any way they would allow us to just keep same the car out and start the second reservation when the first one ends? FWIW I've had some great experiences with the SLC location but I don't know how well this would go over.

Note: the Saturday-Monday reservation is RQ MCLE with CDP# 77694 (USAA) and PC# 107203; the Monday-Tuesday reservation is RQ USGD with CDP#77694 only (since the PC can't apply). (The straight up 3-day reservation I tried was MCLE with USAA and PC# 107203.)

Thanks
