We are so excited to travel to Spain for the very first time (in August)! We are renting a holiday rental home in the area of Cortes de la Frontera, we will be traveling down from Seville on a Sunday. Should we stock up on groceries in Seville or will there be places to buy groceries in Cortes de la Frontera on Sunday afternoon? We have vegetarians, and celiacs in the group....I have done some homework and El Corte Ingles carries some of the items we will need. Is there an El Corte Ingles in Cortes de la Frontera? Thanks.
