Yes, but it will cost a little more.
Definitely you can. Do online reservation is much easy. You can check in online for hassle free. Just hand your print out reservation and you will be directed to your car by passing the counter. FYI: not all but some alamo rental are doing it.
Absolutely. I often rent at the Alamo at the Naples airport and drop of at RSW and do the same in reverse.
