We've been to Cambrils Park - and had a look around Sanguli which is a sister park. Cambrils Park is great - big but for Spain good sized pitches, great toilet blocks, really clean and pleasantly laid out, a super pool for all, and a separate one for children, with squirting elephants! There are all the facilities you would need, on site, bank machine, supermarket with butcher, 'holiday shop' with buckets and spade, and such like, patisserie, cafe, restaurant, bar, sports facilities, etc., etc. You're about 500 yards from the beach, down a rather 'tricky' road, and over a railway (which doesn't cause too much onsite noise) then across to the promenade. There are bars and restaurants nearby, and small supermarkets. I would recommend it. Sanguli is nearer to the centre of Salou, and that is a recommendation for some people.
