If you don't want to queue or deal with the counter staff and avoid insurance offers, Alamo has a row of self-service machines in the rental lobby. Simply input your reservation number, driver's license number, swipe your credit card for the deposit, select 'no' for the other options, and the rental document will be printed out.

Alamo charged mandatory fees without explanation.

Excellent

Communication was not smooth enough, the replacement car was not as good as the original one, and I had no choice, so it was quite confusing.

Avoid ALAMO, only use If the price is rock bottom and you don't mind shabby service. My booking as indicated by Alamo, clearly showed 'Ford Expedition' or Similar. Went to collect one of the many Expeditions in the lot, and was told I would need to pay extra to upgrade to the Expedition, despite it being on their paperwork already...

This is a good firm to use, I will look at other rental firms through this broker :)
