Are you looking for a limo because of the number of people you have? If yes, then there is another easy alternative at Long Beach and at SNA (orange county airport) too. We are a family of 5 (sometimes we have an extra at 6) and we always just walk out to the taxi stand in front of the airports, and ask the taxi coordinator to get us a cab-van. It has never taken longer than 5 minutes, and then one pulls up for us. The price is the same as the cab-it is just a minivan size.
When returning to the airport we just have the hotel call a cab van for us.
It is very simple compared to shuttles for us. I will never take super shuttle again!
We have never done a limo, but it does sound fun.
