At Southampton Central

Leave by the south exit for the taxi rank. City Cruise Terminal is 0.6 miles through Dock Gate 10, Horizon 0.5 miles; Ocean, Mayflower and QEII are 1.5 to 2.5 miles and better by taxi. The coach station on Harbour Parade is a 6-minute walk if you are connecting to National Express.

Luggage on the train

There is no luggage limit on South Western Railway, but the racks fill on Saturday sailings. Travel on a mid-morning train and you will have the space and still make a 13:00 boarding.

Which train to take

Direct trains leave Waterloo from platforms on the south side of the concourse; the fast services stop at Woking, Basingstoke, Winchester and Southampton Airport Parkway only. The slower trains add Eastleigh and a dozen small stations and take up to two hours, so check the journey time when booking, not just the price. First class costs little more on advance fares and has the luggage space. Avoid the 07:00 to 09:00 trains out of Waterloo on weekdays only if you want a seat for the cases; capacity is not an issue at weekends.

Arriving by coach instead

National Express runs from London Victoria Coach Station to Southampton Coach Station in about 2 h 30 for less than the walk-up train fare. It is the fallback when advance train tickets are gone, and the coach station is a 6-minute walk from Southampton Central.
