Dover debarkation timing:

Is it reasonable to think I can make it to Ashford for the 11 am Eurostar?

How have any cruisers found the process of getting off the ship in Dover?I am thinking it docks in the middle of the night and by 7 am passengers can start to go where they have to go. Right?

Most cruises start disembarking at about 08:00 and go through until about 09:30. On a lot of cruises priority is given to passengers booked on the cruise buses going to Heathrow or Gatwick.

Not sure about Ashford, but in London and Paris terminal of Eurostar you have to check in at least 30 minutes before departure of the train.
