Depends who you talk to.
Many residents who do not rely on tourists get grumpy at local areas being rammed in normal times, and so many businesses aiming at tourists with money to burn rather than catering for locals. There are several pubs and shops around here which are basically off limits to us because "normal" people are not welcomed - we are not the demographic wanted. Our bank accounts aren't full enough. On top of that, some holidaymakers (not all, but we do tend to get a certain type here!) treat locals as beneath them and so there is a weird kind of inverted snobbery from some residents. Roads get clogged up and residents struggle to go about their daily activities- awful being a postman along the coast road in summer! And all of that is before you throw a pandemic into the mix.
Those with businesses on the line are quite rightly worried and desperate for tourists to come.
Those who don't are quite rightly scared and angry that business owners seem to care more about themselves and their bank accounts more than the health of other locals.
The kind of areas you are talking about have an appalling lack of infrastructure for roads and public services such as health, as most of the year they don't need as much, so locals fear there won't be capacity for them if needed.
Second home owners and holidaymakers have been demonized by some local residents who see each of them as a potential Typhoid Mary. They are terrified. Knowing we have a huge percentage of the "let's retire to the seaside" population here, I'm not surprised. Especially since cases here have begun to creep up again. Everyone is worried.
Fighting on social media between business owners and residents who do not rely on tourists has been vicious. There has always been a certain amount of strain but this has really brought it to the fore.
People will come anyway so we just have to cross our fingers and get on with it really.
I think it's safe to say we don't mind a few who actually behave with respect to the locals esp re queuing for chips /wandering around with no regard to social distancing/ cramming on the beach. But we would prefer more limited ones than those we are likely to get.
