I posted this very same questions this past March and the consensus was that the alternative to a shuttle would be a cab! I was told to be sure to ask for a flat rate, it shouldn't be more than $30-40 from SNA to DLR. I also use Yourride when I go to WDW so I know what you mean. It seems the Super Shuttle service is more efficient than Mears and that's why everyone uses them, they only carry 6 or 8 people or something like that and they fill up fast and come every 10 minutes. I was told the airport bus is also an option but it stops everywhere and only comes on the hour! I'm too impatient for that! I want to land, get to the hotel, check in and hit the parks! I'm going to try the cabs going to the hotel and maybe take the shuttle back to the airport (no real rush to leave, right, LOL!!) Good luck.
