Just wondering if the Standard and Full size cars at Alamo use the same aisle? I have read on a few other posts that they are actually the same despite the price difference. I have the option of renting a mid size with an upgrade to standard, or paying a bit extra for a standard with an upgrade to a full size. The specs of the cars look the same, 5 people and 4 bags. The last time we rented from them we had a standard (Chrysler 200) and it was pretty roomy. Anyone input on this would be greatly appreciated!
