I have a question regarding National and it's Emerald Aisle service. I know that many people here have said that they have reserved a specific type of car, but with EA you can pick whatever is in the EA at the time you get there. My question is this. If I reserve a full size car will I be guaranteed to at least get a full sized car. What I mean is, as much as I would love driving out a convertible or PT Cruiser or something I am going to be travelling with 3 other people and we will need luggage space etc. I would hope to get something larger than a full size, but will I be guaranteed a full size?
