You should aim to have the majority of your meals with your family: it’s the best way to sample authentic Spanish food and – more importantly – to integrate yourself into family life.
That said, your university timetable may not allow you to eat all the meals with your family. The cities have reasonably-priced restaurants, outdoor fruit markets, etc. As you make new friends, you’ll want to try some meals out on the town. This is perfectly fine and normal. So if you’re not going to be eating with your family on a particular afternoon or evening, you should call well ahead of time to let your family know – the night before, if at all possible.
