We had a great few hours exploring the whole place. You start on the 3rd floor and work you way down which means you don't miss a thing. You get to see all the tanks from several angles which is good. And it's all very clear and well maintained. Lots to see and you can easily spend 3 hours + and still see more on a return visit.
My one year old loved this. Seems to be well placed for all ages. You got or old! Very much worth a visit.

Tickets... are for a year which is really good. Cues can be long but they go quick. No more than 20min cue. (Seems silly tho as we booked online first yet could not skip the cue)
