I've been an emerald club member for almost 10 years and I stay because of the emerald aisle. What I loathe about this location is that all of the elite/executive aisle cars are all in fact midsize and all of the luxury cars and SUV's are in the emerald aisle.
What's the point of getting to elite to get access more vehicles if I can get them as an emerald club member?
Some of the staff are really helpful and others will go out of their way to treat you like family. I wish I could remember their names but one is a male manager of south or west indian decent and the other is a woman at the gate of caribbean descent.
Even with my gripes, I still love national and it will always be my go-to for car rentals.
