Europe Sites Guides- which ones are best?

Our first Europe trip starts in January, taking our caravan from Caen down to Southern Spain then back early March. I have the first night stop near Caen booked (thanks for all previous help) and a 30 day stop near Malaga, we then have another month or so which isnt booked anywhere yet. I have joined ACSI so will be getting their guide. My question is will this be enough or do you recomend getting the Club books as well.I have been looking at the club website at the Caravan Europe guides, I would need Vol 1&2 so cost approx £15. Is this going to be money well spent?
