The Deep is fantastic first time around - as long as you don't go there expecting it to be like Alton Towers or Disney Land. It's a big tank full of fish, but they make it as interesting as a big tank full of fish can be!
I must have been there 5 times now, it's kind of become a tradition, just like shouting "BRIDGE!!!!" as we come round that bend on the A15 and see it

Got a friend runs one of the bars in the centre, we get up there normally a few times a year. God knows how we get back
