Carnival Shuttle LAX To Carnival Port By Cab? (10 Pts)?

LAX to Carnival port by cab? (10 pts)? - carnival shuttle

I am the Carnival Splendor Cruise in August and fly to LAX. I wonder if anyone took the trip by taxi and if so, at what price and for long as the journey. I'm trying to compare prices shuttle carnival, the $ 27 (is far) about the price.
There are four of us go, I have compared with the $ 108 price for a taxi, taking into account the ease it offers shuttle carnival do not have to wait in line for baggage port.

Thank you for your help!
