Booking France for 2018

Hi, just back from France on our first motorhome trip. We enjoyed it so much we are planning to go back next June. When is the best time to book, options welcome.
Thanks

I think it all depends on the time of the year, main holiday times I think you should book early. I was lucky with regard to price this year. I booked on the 11th of April to sail Rosslare - Roscoff on the 11th May and returned from Roscoff on the 22nd June. The price was €410.00 including 2 berth cabin and the flexibility option. I was pleased with the price. This was for me and my wife.

I was under the impression that if you book through the advert on the club web site you get 10% off ,can any one enlighten me please.

Sorry i hit something early and posted and cant edit. As mentioned above accommodation is the main problem when wanting to return at the end of June before summer pricing kicks in or go out at the end of August as prices drop, We have done 2 trips a year for 6 years now, we book flexi just encase for €15 each way and have used the edit a few times once due to bad weather. They lash down lorries but not car or campers .
We got an Irish seas offer for 2018 and the ferry with accommodation with flexi both ways was Booking Total: 392.40 EUR from Rosslare
Have not booked the Autumn trip yet but reading above from Mark will look at it.

Thanks for the info, have just booked
