We used Last minute travel (called 888 number on website) for a 5-day PH for my mother in law (we have APs) and saved $38 over aRes. We also use Execucar (a Super Shuttle company, but with non-stop service) for our party of 4 from SNA to the Grand and it's $66 one way inclusive of tip. They text me when we land, meet us in the shuttle loading area across from the American Airlines baggage claim and off we go. We've had fantastic service each time. I've used Uber in the Anaheim area and it's been great too. I've not done the airport through Uber. Can Uber pick up at SNA? Some airports still have restrictions on ride share services.
