Hi Xavier
We recently joined the Frequent Virgin Club. If you book on-line thru Virgin Holidays you will get a 10% discount on the adult price. When you get to the end of your booking they will replace (I think at a later date) the on-line discount for the FVC discount.
Now, we have booked next years holiday and we rang Virgin direct and got 10% off the total booking.
Have you actually joined the club yet? It took about a month for our membership cards to come thru, the family got one each along with a hand luggage card, then we recieved one rather nice Virgin backpack (I claimed that) which came at a later date.
I hope this helps
