The last few times I've taken the Disneyland Express bus at LAX I've noticed something shady.
There are minivans that say "Disneyland Express Shuttle" and "Mickey's Space Shuttle" which aggressively court the people waiting for the real DE. While we were waiting, on one instance, the driver came up and asked if I had a voucher, as though he were the real DE. On another instance, the van raced in front of the real DE bus to try to beat him to the terminals - and then the driver was actually going down the line and trying to pull people away to get into his van.
From what I've seen these minivans are run-down, the people are packed in like sardines, and Heaven only knows how much they charge. The question is: why are they being allowed to mislead people into thinking they are the real, Disneyland-endorsed Disneyland Express?!
