Late to the thread. I have lived in perranporth for 14 years. I love it (and have come from a big city - met a cornishman and stayed). Perranporth is a beautiful town with lots of lovely people, very family orientated and the school is brilliant (but often full). My kids (pre teen and teen) love the community here and have lots of clubs and activities they do.
In the summer it is a buzzing place, lots of small businesses, pubs, restaurants. One time, just after covid, perran got too full and the police stopped people, this is not a regular thing. Yes, it gets busy on summer days however being local you go to other spots locally where tourists do not. Yes sometimes the summer holidays brings problems however we get the beautiful place for the rest of the year, and a lot of local livelihoods rely on it.
If you like the bustle of a city, probably not for you. If you like nature, outdoors and a strong community then it is a great place to live. The winter weather can be hard, but we don't mind this.
There is a strong home schooling community in cornwall and I know a few people who do this and have really good networks.
It's about researching whether it is the place for you and your family, and whether you can secure housing and jobs.
