Holiday on the Buses

An evening of the on the buses films. If you want to be reminded of c1970 Essex just the stuff. The buses were Bristol KSWs from the Eastern National company. An OPC book called The Bristol KSW dated 1985 gives the exact details of the four vehicles used (plate 74). Holiday on the Buses came last and somehow or other I felt I had missed this previously. It is evidently filmed at Pontins Prestatyn and used a Crosville open top Bristol Lodekka. However for my tastes there is some extra-ordinary footage of storm tossed Sealink ferry. Clearly bought in and very dramatic. Was the vessel Holyhead Ferry 1 see http://www.sealink-holyhead.com/railway/ships/ferry1/home.html ? An answer to that does interest me.
