We didn't have the negative experience a couple of others had - where the writers said WallyPark lied and cheated. However, be aware that there are three different WP lots. You're not told this when dropping off your car so therefore aren't aware you should be looking for a particular van when leaving the airport. The driver of the first van we got on was nice enough to let us know and alerted the other driver to look for us. He said it's a common problem and would be so easy for the management to fix. Otherwise we had no problem. But from the other comments will surely be on the alert next time.
