Have used both National and Dollar over the last 5 years but think I prefer Dollar anymore over National. Dollar seems to have a good rate on mini-vans a lot of the time, and with 2 sets of golf clubs, plus bags, it is nice to have the extra room. We have used their FastLane and have been impressed with their service. Last trip in May used National and thought the workers were rude and not helpful. Arrived at 1 a.m. and EA was short on EVERYTHING - basically only had pick-ups to chose from. We had reserved a full size car and the attendant finally found us something to use. There were lots of vans on that aisle, but he wouldn't let us take one. Last December, with Dollar, had a compact reserved and none were clean, so attendant asked if we would mind taking a mini-van same price. Yeah, right! Anyway, I think I prefer the customer service I have received with Dollar!
