Eavesway operate a service from Glasgow for all P&O sailings, However if you should wish to fly to Heathrow they have a service which operates from there as well. Please see, www.eaveswaytravel.com or ring 01942 727985. Hope this will help.. Steve Eavesway Driver.
If this is any help, National Express run a coach from Heathrow coach station (near terminal 2) to Southampton coach station, then 5 to 10 minutes in taxi to docks. times prices etc on their webpage .
Hello there - I don't know if this will be of any help to you as you make your travelling plans but I wonder if you are aware of the direct train service from Edinburgh/Glasgow to Southampton from where you can easily get a taxi for the 5 minute ride to the cruise terminal. However, should you decide to go via London then yes, the train for Southampton does go from Waterloo. Another option is flying - I have met several people from Scotland who have flown directly to Southampton and then on to the terminal by taxi. I'm afraid I don't know if there is a direct flight Aberdeen/Southampton bit it's worth looking into. I think I am right in saying that Eavesway coaches only operate from the North but don't know if this includes Scotland. Enjoy your cruise. Regards - Janet .
