I have visit two SeaLife Aquariums: Bray (Ireland) and Benalmádena (Spain). Both quite small and with very similar style.
I think they are fine for families as a place to spend the day but definitely out of the question for anyone really interested in zoos or aquariums. They don't really have anything special and I find the whole style quite repetitive.
I would still be up to visit more SeaLife Aquariums in the future if I am near any of them and I have a few of them on my bucket list actually (The one in Iceland working as "beluga sanctuary" might be curious to visit in order to see how they have adapt all the area for belugas)
