We used lyft to get to and from the parks in our trip earlier this month. It was super easy to use, cheaper than a taxi or rental car, and way more time efficient than super shuttle. The cost was about $25 total and it took less than 30 minutes to get to the parks. Lyft/uber also have plenty of discounted ride deals for first time users if you haven't used them before. SNA is one of the few airports that allows lyft and uber to pick up passengers so it was really easy to request a ride and figure out where to go.
We used the regular lyft service for 4 people or less so it will be more depending on how many friends you have.
