Hi, I have never rented a car before and I am planning on renting an SUV with Alamo at the Orlando airport at 4PM on 8/22 and returning it to the Dolphin at 1PM on 8/27. Is there anything special I need to know or be concerned about? Like I said, I've never rented a car before so I have no idea what to expect or what some pitfalls may be that I need to consider. Thanks!
