Hi Buzzlightyear3 We've used Alamo in the past. You should be aware that we've used Alamo, Dollar and
Avis,(we prefer Avis), and you may want to reconsider, unless going off-site and standing in long lines is worth saving a few bucks. Alamo was terrible. We stood in line for over 1/2 an hour, (after a 10-15 minute shuttle bus ride). You also have to lug,(pun fully intended),your luggage onto the shuttle bus, and keep a eye on it while standing in line.
Both Dollar and Avis are on-site, which is very convenient. Alamo and Dollar, also have a $5.00per day surcharge, (even if it's your spouse), for additional drivers. Avis doesn't have this surcharge, as long as it's a spouse. JMHO If you haven't already done so, you should join one of the preferred renters programs, (i.e. Avis Preferred, or Dollar Fastlane). It doesn't cost anything to join and is very convenient. Hope this helps!
