Coming to Ibiza for the first time in late August (Cala Tarida) with 2 kids (ages 1 and 3) and will be renting a car to explore the island but quite fancy a one day trip to the mainland (Valencia) as I used to live nearby (Castellon de la plana) and fancied checking out some of the old places I used to go. Does anyone have any info on ferries to the mainland... times, prices, how long it takes? I really want to go but I have a feeling it's not the sort of trip I can do in a single day
