We are an English family looking to spend some time in Grenada in Spain and will rent a house there for three months initially. We want to try it out before committing to a more permanent move. We would be in Spain on the basis of the 90 day visa-free period. Has anyone had experience in enrolling their kids in school without having a visa post Brexit? Do you just require proof of address (along with the usual proof of ID documentation)? Many thanks.
