We aren't that quiet...but we are Eurocamping in Italy (Venice). We have 3 kids too and flights were £300 and we are tenting it for £850 but you could get a mobile home for under £1300. Our site is on a beach.
This is just £200 a week on a 5* resort and sleeps 5. Swimming pool and tennis court right next to it but beach is 15 mins drive. Could afford car hire at that price thought and beaches are blue flag, its the Mar Menor which is lovely
