Hello! My boyfriend and I want to go to Madrid, Sevilla, Granada, and maybe some other places in Andalucia between 16 and 24 September. I don't know if I should make reservations for accomodations right now or just wait until we get there. I don't want to wander around for hours hopelessly looking for a place to stay, but I don't want to totally plan out our trip either. I read that September is still high season in Spain. What do you think?
