Boat everytime!! Planes are faster, but the amount of time that you need before the Flight at Airports nullifies much of the saving. Also the Airport, Harbour. Where is it compared with where you want to go!? Stansted is a long way from Kent, whereas Dover is just right. The ferry crossing is time to have a snack, relax, do some shopping, look out of the Window and watch the White Cliffs approach, a magic moment for us both. We don't use the Rat Hole, as it is far too expensive (Approx 4 times the equivalent Ferry price) and so unreliable. and it is not that much faster, you might save 25 minutes or so, but against that you have to sit in your car as the Train rattles its way under the Channel. No Toilets, no chance if it breaksdown. Which it does, regualrily!!No. Ferries for us please, and we have been crossing the Channel for more than 35 years, and have gone every way there is or was, including the Hovercraft, now that was an experience!! Faster crossing ever, 25 minutes, like a monster Roller Coaster.
