I think if you live by the coast you have to accept there will be lots of tourists in the summer. There are pictures of packed beaches since Victorian times.... This is Brighton!
We do!!!!!!
OP wants to escape to somewhere quieter this year. Not sure why that’s so controversial 
I love it here in the summer, I love the buzz tourists bring with them. The place is dead in the winter, in the summer it all comes alive, although I do breathe a bit of a sigh of relief come the end of September when it quietens down and it’s peaceful again.
We work round it, go to the supermarket and town early, avoid the tourist attractions and go to the quiet, off the beaten track beaches. We’re all well used to the busy summer season, and given our economy is based on tourism, welcome it.
However, I’ve never witnessed the kind of behaviour we experienced last year. I’ve lived here all my life and I’ve never had people pissing or shitting in my garden, I’ve never come home from work and found a visitor parked on my drive, I’ve never found a tourist trying to ride my arthritis ridden, elderly, retired pony and then been verbally abused and physically threatened when confronted, I’ve never witnessed the litter, vandalism or destruction we experienced last year.
I want to go away somewhere a bit quieter this year. We were hoping to go on a bit of a road trip this year. We were waiting to hear when year 11 DD is likely to finish school so we can go out of the school holidays, but am worried we’ve missed the boat
