Rally in France

Does seem very expensive, £935 incl £40 rally fee + insurances etc, I have booked the same site for 14 nights in July, with a much more time convenient overnight ferry crossing (Plymouth- Roscoff) for £593 + insurance. What would I get extra on a rally for my almost £350? By the way on the Alan Rogers website this rally is even more expensive.

I thought that joining a centre rally was away of meeting new people having fun but since Alan Rogers has started running rallies the prices have gone up I now try to avoid any thing to do with Alan Rogers

I find this very difficult to believe as I can't book a crossing for less than £520 on a weekend in high season then you have 14 nights at the site!
