I must admit to an outsize hypocrisy over P2P/D2D. I deplore the D2D concept, not for itself (even though the included elements carry a huge mark-up), but for its promotion at the expense of those of us who prefer to make our own arrangements.
And now I've only gone and booked an expedition cruise on the Wind which is only offered in D2D. In my defence, it was an offer from a UK agent that was hard to refuse.
But I can't help but feel slightly soiled by being a traitor to the Provisional P2P Army.
