I am reserving a full-size from National. If I get there and the aisle has a van, could I take that instead? I know that "reserve "means you get what you reserved, but last time we were on the aisle and there happened to be a van (it arrived after we had loaded our stuff into a car). We snagged it and were very happy about it. I can't find any decent Internet rates for a van for our week (Aug. 12-18). Thanks!
