Great attraction. Perhaps not a whole day out, but certainly an afternoon. There are often workshops running, so worth checking before visiting.
The whole place is buggy and wheelchair friendly and there are stepping stools to give smaller children a boost so they can get a closer look at the exhibit. A wide variety of sea life to spot.
Your ticket entitles you to repeat entry too, so if you live locally it's well worth the admission price (not sure if you have to specifically ask for the annual return ticket, or if it's just automatic?)
