I am looking to visit Dover Castle on a Saturday in July. I would like to take the high speed train which leaves at 8:37am from St Pancras station taking 1 hour and 5 minutes. Do I need to book tickets in advance or can I purchase them the morning of the trip? Also, I looked on the Virgin Train website that was suggested in another post and their prices are higher that the Loco2 or GWT websites? Why would that be? There are 3 of us traveling and Loco2 seems to give a group discount.
Also, we will be returning the same day in the evening. Do I need to specify which train or will open return work?
Thank you for any help.
