If you are returning on the Brittany Ferry it is well worth getting to the port several hours before departure. If you miss the ferry the next one is in 2 days time. You can check in from 09.30 and park on the dock for free. Your cabin ticket has a bar code on it which allows you to come and go through a turnstile gate. A short walk along the front brings you to the tourist information office opposite the Santandar Bank HQ. A hop on hop off tourist bus operates from here every 30 minutes and cost 14 euros. We got on and off at several stops. The bus was always on time and Santander is very nice. We then sat in the small park opposite the port and had lunch before going back to our car just before boarding.
