And not only do friends lose the bit of discount but we also lose the £10.00 from each booking, but heyho.
It's still worth being a member but only just if you only use them once, but as a large supermarket chain says, every little helps! We try and use them at least a couple of times a year, so with the crossing and onboard food discount it becomes much more worth the annual fee.
Break even is once a year for us, but if you left and rejoined at a future point you would have to pay the joining fee again.
I haven't read all the T&C's, but I think there might be slight differences in the benefits for new members compared to long term members.
