Summer 2013 when can we book (c:

Okay, so this is probably one of those questions that gets asked year on year.....

When can we book for Summer 2013?  We know where we want to go and indeed what dates, but you can only currently book into March, is there a 'release' date for booking the summer dates?

We loved our summer so much this year thanks to Caravanning and in particular the Club so cannot wait to get our choices sorted.
