Hilton Head bike rental companies are up in arms about a fee hike Sea Pines Plantation will implement this week -- a hike the companies claim is unfair and illegal. Decals for the vans that deliver and pickup bikes for Sea Pines tourists are set to increase by as much as five times. One bike rental shop owner has already hired an attorney, who says the practice is an unfair manipulation of trade that will ultimately hurt Sea Pines visitors who will be charged more for bike rentals to compensate.
