Would like to hear from anyone that has done on site car rentals, inparticular with Alamo and National. I was wondering how good the selection of vehicles available and does National have an Emerald Aisle there at the Dolphin? Any comments on other companies also would be appreciated. I would like to do a three day weekend rental so we don't have to rush for some special ADR's we have made (one is for my DS on his golden birthday - turns 10!) Thanks!
