You can get 2 for 1 tickets online with national rail. Just google 2 for 1 london aquarium. We went with DS recently for his first birthday and it was a blast. he LOVES fishtanks, though.. was heaven for him. And he was free, so just £16 total for the 3 of us.
If you go by train you can get 2 adult tickets for the price of one. I think it's pretty good but I would plan to do something else in the day just to make the most of being in london, like the science or natural history museum (both free I think).
MrsJamin - your post was much more helpful, though - with the link included . Agree that the other museums would make it worth it and they are both free. Science museum is WELL worth it. They have two hands - on play areas. "The Garden" downstairs (way downstairs) is a play area for 3-6's I think. We have brought our DS (just turned 1) there a lot and he LOVES it - there's a water table and just loads of really fun and intellectually stimulating stuff for small children. There's also the "pattern pod" which is fun, but not as much fun as "the garden" - both are inside play in the museum and FREE.
timmette - when we went, we just got the voucher online and presented it at the counter. They never asked to see our train tickets. We just had zone 1-6 day passes, in fact, so no proof if we took the train or not, really anyway. It might be worth just registering really quick and printing out the voucher online and bringing it with you - you don't ahve to buy a train ticket first or anything. Just a though to save you some money as it is expensive.
def not worth the price of admission - it's dirty and v overpriced. there's nowhere to stop if you want a snack (tho can go back in and out when get hand stamped) toilets were horrendous and unless you go as soon as you enter you have a long wait. I'll never ever go again!!
I guess we're easily amused It has been redone just recently - so if you went a while ago it may have been dirtier? It was nice when we went. DS ran all over the place and had a blast looking at all of the fish.
Oh that's not good I will need the loo being almost 8 months pregnant then? Does anyone know when halfterm is in the UK as I am living in Belgium at the moment and was hoping to avoid huge crowds - we were thinking of going 5th Nov.
It is much better than it used to be. My children love it. We were there about a week ago and I thought the the loos were rather good. Also, I like the fact that you are through it in an hour or two because children that age start losing interest after much longer. It is expensive though but if it's a nice day you can have lots of fun pottering around on the south bank afterwards.
Thanks everyone didn't want to spend a whole day there just an hour or two - that's about his attention span - lol. I have decided if I can find cheap tickets we will go - so on a search of cheap tickets now. But thanks so much for all the advice.
