Just phoned Caravan Club for a Larne to Cairnryan return and the price they quote is for a fare that can be amended for £20. Only thing is , the fare on the P&O site can be selected as a flexi ticket for an extra tenner on the return trip which is still cheaper than the CC quotation. their promise printed on their web site is:- We guarantee to match or beat fares offered direct from ferry operators. Total Bo****ks. I know, I should hold them to their promise - but could not be bothered with the hassle as when I asked about the flexi ticket, they told me the only price they had was the one quoted.
