At the end of the M3 motorway is the Hilton Hotel at Chilworth. There you can get a room, dinner, bed and breakfast, car parking for up to 14 days and transport to and from the dock for £150 to £170. (I am reliably told that a little negotiating with the receptionist could get the price, on certain occasions, a little lower. Hope that helps....Nei.
We are also going on the cork cruise (Independence of the seas) we are staying in the holiday inn which is alongside the dock. The parking is about 60 pound and accomodation is cheap. It is the ideal location, as we will just simplily walk onto the ship instead of the risk of getting stuck in traffic.
