When my children were younger, often used to have a week at Butlins in Minehead. Long drive for me from Essex/London borders.
Back then ALL holiday bookings were Saturday to Saturday. Friday nights was a Special End-on=holiday gala night. This would go on until midnight,. Saturday mornings were so dismal in a holiday camp, with EVERYONE packing up to get away as they all had to leave their chalets by ten in the morning,.
I used to allow ALL my children (except the babies) stay up to join in the whole of the gala night. Before we went got permission to bring in my car close to the chalet (not allowed Saturday mornings) and get most of our stuff packed before we went. Came back just after midnight, hot drink for all, then children washed, teeth cleaned and in nightclothes and we would set off home at one on the morning. Would have just one short stop (as we went onto the M4) for toilet for me. Apart from that drove directly back home,.
They all fell asleep during that journey home and the motorways were pretty empty during those early hours of the Saturday. Would arrive back home around 5 am and would listen the following day to the reports of all the hold ups on the roads we had driven through.
