Thanks for the info.
I did check in to dropping off at the Dolphin, but my National rental from Sunday at Tampa airport to Tuesday at the CCC is $59.
Same car, same pickup, drop off at the Dolphin is $129.
Guess I'll call a taxi.
I will be dropping off a rental at the Car Care Center, but it will be after hours so I have two questions:
1) Where exactly is the Car Care Center located?
2) How can I get back to my hotel if I drop off the car after hours?
Thanks for your help!
