I have called both companies. Travelynx charges 25 pp and Cocoa Beach Shuttle charges 27 pp (including the 10% discount for mentioning Cruise Critic).
We arrive around 9:30 am and both companies told me that they wait until they have a group who have landed around the same time going before they leave for Port Canaveral. Cocoa Beach said the wait time would be around 30 - 40 minutes. Travelynx would not specify a wait time.
My primary concern is a reliable company who will get us to Port Canaveral in the most efficient manner.
Does anyone have an experience (good or bad) with either company that I should consider before making my decision?
