We have a static caravan in a 'chav city' seaside town. We bloody well love it. There is absolutely tons of stuff to do with DD - the beach, the dunes, a fair, a splash zone, a pool, amusements, animal farm, play park, adventure park, pier, horse riding and the evening entertainment for children: Magic shows, balloon shows, Crazy Kev & Dinky, Mr Mayhem, Chunky Russell, Nutty Noah - bloody hell there are hundreds of them!
We have all that plus time to ourselves when she is playing with other kids, peace and quiet, a comfy caravan, 15 different bars and restaurants, live music, comedians, party bands and the odd Z list celeb (X Factor 'losers', BGT finalists, Shane Richie Junior)
Sure there are lots of UJ shorts and vests, plenty of drinkers, some choice language and smokers...but there are also a lot of decent people who love their kids and want them to have a good time. Lots of people that know how to have fun. Lots of people that couldn't give a damn what other people think of them. Lots of people having a well earned holiday and making the most of it - no matter what the crappy English weather throws at them.
I could tell you to take that stick out of your arse and have fun. But I have a feeling you've already judged it and found it wanting. So you'll be unhappy in any case.
