Quick MN search suggests you've both been. We're going to Vilanova park with Eurocamp on Thurs.
Will obviously spend a couple of days up in Barcelona, also thinking of visiting , Tarragona, Sitges & Salou. Any where else you'd recommend? Port Aventura sounds worth a visit - have you been? (DCs are 15 and 10) and also would like to knwo if there are any good waterparks (Costa Caribe??)
