Providence, Rhode Island National Car Rental?

[happily single]

Thanks to a Dis'er here I was able to score a great deal on a rental through National Car rental, picking up at the airport in Providence, RI (well actually Warwick, RI but shh). I have always rented with Hertz and Enterprise, and both were local to me and not in the airport.

Can anyone tell me about their experience with National in Providence? Does Emerald Aisle still apply?
Thanks

They do have Emerald Aisle in PVD.
