As a seaside town resident I totally agree. Public toilets have mostly disappeared and those that are left are stupidly expensive.
Parking charges are unbelievable and not even legal in many cases as the council have not done the correct paperwork when they introduced them or marked the roads correctly. Meanwhile the road surfaces are in the worst state I've ever seen them as the council spend all the money on addng new traffic lights everywhere and turning a 15 minute journey into a 30 min one even when traffic is calm.
As for cafe's and things - my advice is to avoid anything thats anywhere near seafronts and other major tourist areas.
Also make sure you have enough petrol because prices are higher here. In fact just go 1 hour inland and everything is cheaper and better quality.
The annoying thing is that residents are hit by the costs just as much as visitors despite this being a town with an average income below the national average, all because every retailer wants to fleece the tourists.
