I lived up and down the UK over 40 years and found people to be friendly everywhere. The one area I found less receptive of anyone with a different accent was north Wales. Even going into shops if you even said Hello on entering and if there was another customer in already they reverted to speaking Welsh even though I had heard them chatting in English on entering. Happened in a lot of places. I admire the Welsh for using their language but to obviously so deliberately change was to me very rude. Thankfully was only there for a year.
Your next holiday must be to where the first holiday you remember , where are you going?g
