There is no charge to actually ride the pods so you can hop on the pod at Terminal 5 and ride it to the car park but without the code to get past the gate and into the hotel, you'll just be stuck in the car park and have to ride back to the terminal. If you're staying at the Thistle hotel, you'll need to contact the hotel and they will give you a code to get through the gate when you arrive at Station B and add the cost to your bill. If you're not staying at the hotel (or parking in the pod car park) but just want to ride the pods, then that is totally free.
