Strange. I see a lot of adverse comments here about Eurotunnel. I use them a lot and I've never had any problems, and don't find them much more expensive than ferries, except for the ones that go at some godforsaken hour of the night, which I just won't use. Really is my preferred method of crossing, so I'm puzzled
I too used to be a fan - it made Brakkers to Montpellier an easy run in a day, without having to hammer it all the way. Used many, many, many times, with no issues beyond the usual 1-2hr delays that seem to plague it.
But they will do *anything* to invalidate your return ticket, so they can arse rape you on the return €299 one way. And the promises that "Customer Services will sort it all out when you get home" is crap, as like Chinese Ebay Sellers, all of a sudden they lose the ability to speak English.
The time "saved", assuming no delays, isn't really a saving, as the ferry allows you to grab a meal, thus not have to stop again for food.
