Choose destinations wisely. For example Dublin - I found it lovely and friendly and lots to see, BUT I didn't go near Temple Bar or anywhere in rip off land. I don't recall paying 15 for a pint or a drink either, but like any city you will pay for the privilege of being a tourist!
I am lucky enough to have travelled a lot and can honestly say that I took something positive from every place I've been. Yes some of them were not great but still. Having paid a whack to get there, I made sure not to moan too much and find something nice. LA is a case in point. Legged it to Redondo Beach on the bus lol, and took the greyhound bus to Anaheim and Disney with zero intentions of doing so at the start. All to get out of LA itself. It is a shithole no doubt about it.
All places that I didn't like were tourist traps, places where no one cared one bit whether they provided good services or not, and were rather blase and sometimes angry with mass tourism, but the money was coming in anyway!
Worst place was definitely LA, closely followed by San Fransisco, but made it out to Carmel and the wine country across the GGBridge so avoided the horrible sad mess that is the homeless and drug addicted streets.
Am glad to be able to travel, so should you 😊
