Brittany Ferries, club voyage

I’m thinking of joining Brittany Ferries club voyage Spain. First year cost is £180, their website states than you get up to 30% off cost of ferry. What are your experiences of this, what are usual discounts, basically is it worth it.
We are travelling March-June and then September-November this year.
Thanks

Hi
If you are doing 2 return trips it probably is.
I just do 1 return trip a year now and still quids in. Don't think the benefits are as generous with latest club voyage as were previous ones.
Maybe check the fares for dates of travel and deduct 30% and see if its more than the membership fee. I get €25 per trip on board spend as well which helps the bar bill Ray
