Ferry or Shuttle

[dspuk]

Thanks everyone. On the dates I'm searching the tunnel is coming it at £300 return vs £150 for the ferry, which I'd notice.

Some of the replies mention that if you show up for the shuttle and there's space on an earlier one, you can take that. Is that a feature with any fares, e.g., the standard ones too, or just with a flexi fare.

For me the £75 more each way is a lot to save an hour or so, especially as crossing water on a ferry has a certain romantic appeal of leaving/coming home. But rough seas would change the calculus. Does anyone know how often a crossing is rough enough the average person notices and especially how much does this vary by time of year?

Any fare.
