Think thats the way the conversation ran earlier in the thread lol
Here's some info my dh put together for a different board - hope its of interest .....
If anybody wants any tips of what to do in Dover or nearby for a day or two either side of the cruise I'd be happy to help.
For starters I'd recommend a trip to Canterbury with loads of old buildings, city walls and a fantastic cathedral, but a better choice if you have a few hours to spare might be a trip to Dover castle. It's huge and has things to see spanning from a Roman lighthouse, though medieval keep and castle to a secret World War II base.
If you want to visit DLP as well, a good travel option, as already mentioned, would be Eurostar. You can catch it from Ashford direct to the gates DLP, and the station in Ashford is only a 20 minute or so drive up the M20 from Dover. Or you can get a train direct to Asford from Dover that takes about 30 mins. Then it's 2 hours or so to the gates of DLP, and MUCH less hastle than getting a flight from the UK to France.
When we were on the Med. cruise I could never understand why the 'Home' port was Barcelona and not Marseilles as there is a direct TGV service from Marseilles to DLP that takes about 4 hours. It would have been really easy for DCL to organise joint Park and Cruise packages similar to the way they do in Florida.
It's quite a way [London to Dover], I'd be prepared for a couple of hours on the transfer coach, but you might get lucky with the traffic and it could be a lot less. The fastest train connection I can find from Gatwick is a little over 2 hours, and from Heathrow is about 2 hours and 40 mins. From central London to Dover is about 1 hour 30 mins by train.
If you are going directly from the flight to the cruise and are driving or getting on a coach, then I'd recommend coming in to Gatwick rather than Heathrow, Gatwick is much closer to Dover and the drive from Heathrow takes you through the worst bit of the M25 (The London Orbital motorway).
The only other thing that I can suggest is that you avoid going straight from the airport to the ship on the train, The transfer from Paddington to Victoria or Charing Cross if flying into Heathrow, or the change(s) involved going via Tonbridge if flying in to Gatwick would, in my opinion, be quite awkward and stressful, especially for a family with lots of luggage.
If you are having a night, or more in London before getting on the ship, I don't think it really matters which airport you come into, and getting the train isn't as bad an option as it is from an airport to Dover as it is direct from central London.
I guess it looks like I'm following DCL's advice and suggesting that a night in London before the cruise is a good idea.
If you want to find out about train times here is a good site to check out.
National Rail Enquiries - Official source for rail information, UK train times and timetables
Although by the time the cruise comes around there will (allegedly) be a high speed train service from central London to Dover. And the high speed trains will depart from St. Pancras station, which is worth a visit in its own right.
