Hubby was looking online to find out if you can tour the really old ships there and the most he could find was that you had to buy a ticket for 55 pounds that was good for a year, and that let you see the ships, a museum, go on a boat ride and a few other things. Is this the only way to see the ships? I am not really interested in them, certainly not 55 pounds worth! He would be happy to see them from the sidewalk, he doesnt really feel a need to go on all of them. So can you buy a ticket to go on perhaps one ship only and do none of the other things? Or is it an all or nothing deal?
