The “outcomes” you ask about are whatever you choose to spend your voucher on in the restaurants or cafes on board the ship. You choose what takes your fancy, whether you are hungry or not, and whether the sea is rough or smooth. You choose.
What is this new voucher scheme? The only one I've seen is that you pay for a food voucher up front and get a few pounds extra on top of what you've paid eg pay £50, get a voucher worth £55 (made up example). Only worth it if you're sure you'll spend that much (or more).
Don't forget to leave a review of the French and other European campsites you have visited!
I too was wondering if it was worth getting food vouchers and if any users could comment, but I think the system is too new and people haven't commented.
For example I wondered what happened if you didn't use all the voucher, would it be refunded or credited to your account?
Amazing family weekend with old steam engines, classic car displays, market stalls, and full catering and bar. And camping on site - Save £25 by booking in advance.
