OMG Butlins! We used to go to to Minehead ( Bournmouth was too close to home to Portsmouth and wouldn’t have seemed like going away) and as a kid I absolutely loved it. I remember having our meals in these big halls on long tables with all the other holiday makers. The free funfair, the penny arcades, chasing the guy dressed as a pirate and throwing him in the pool. When you arrived you were put in a different house (a bit like Harry Potter) and we used to have friendly but very competative competitions against each other. Glamorous Granny and knobbly knees competions and not forgetting the free entertainment, comedians, singers, magicians, dancers and of course the Red Coates. Kids today would just roll their eyes and carry on heads down engrossed in their phones.
The swimming pool with the large glass viewing panel so that you could see under the water like you can do in seaworld to look at the sharks. You went to one of the areas/bars where you got a drink to see it, all the people’s bottom halfs and ocassionally whole if the swam underwater, which I’m not sure is still there or would be allowed today.
We did go to Pontins (book early as Fred used to say) Southport one year, but it wasn’t a patch on Butlins so went back there the following year.
