We just used them back in May from LAX to Disneyland. It was just DH and I, but it was cheaper than Uber/Lyft and their pick up spot was right outside baggage claim, so it was convenient to catch it from the airport. That was the pro. The con was that it took what seemed like forever to drop others off before us - we were stop 4 of 6.
On a related note, has anyone used the new rideshare shuttle at LAX? Apparently it shuttles rideshare passengers to a lot where the rideshare vehicle picks up from, but I have heard its overcrowded and a bit of a nightmare. Got me wondering what the best way to get to DL from LAX is now.
