Is the Templepatrick Paradise Walk Park and Share the same as Ballymartin?

No.

Paradise Walk by the A6 Templepatrick Roundabout is listed as a Park and Share, while Ballymartin on A57 Ballyclare Road at M2 Junction 5 is a separate bus Park and Ride. They serve different purposes and are not interchangeable if someone is waiting for a bus at a specific stop. Agree the name and road with the person you are meeting and use the official signed car park rather than the roundabout shoulder.
