Super Shuttle Port Pick Up Time After Mexican Riviera

[Disdude]

We are doing a MR cruise in a month. We are flying into LAX, taking Supershuttle (or Primetime) to Fairfield Inn in Anaheim, Supershuttle to the cruise port, and Supershuttle to LAX. What time should we arrange for pick up at the port to go back to LAX? I think our flight is at 3PM.

Thanks
