These two girls (names unknown) are in Skegness, at the Butlins Skegness Holiday Camp. The Holiday Camp in Skegness opened in 1936, here's a link to the Bygone Butlins website. There's a lot to look at on the Bygone Butlin's website, the then and now photos/postcards are well worth a look, sadly the monorail has gone and it does look like there are a lot more roads and car parks than used to be the case. If you go to the end of the slideshow and count back 9 images, then you'll see postcards of the pool where these girls are sitting, though I would think this photo predates the postcards. Actually it's made me quite sad seeing how good it used to be, it must have been wonderful to ride round on the monorail and see everything that was going on. As for the badges, I have the 1959 Skegness badge, (although I've never been to Butlins).
