Was just able to reserve r/t transfers from SNA for 4 people @ $56 total by using code I found on AMEX website. Here's the link: http://www.americanexpressofferzone...spx?oid=2211&searchtype=merchant&countrycd=us It's basically $3 off per person each way...so in our case a savings of $24. I was going to use a cab but this would be cheaper. Note: you must use your AMEX, also there is an area to add gratuity and they make it look like you must add 18%...just change the amount to $0.00 (we did this because we would rather hand the driver a cash tip based on performance). You can cancel up to 4 hours prior to pick-up and receive a full refund.
