We visited this attraction as part of the Adventure Pass which enabled us to get a discounted rate on the admission fee (compared to if we had bought at the kiosk directly) and meant we didn't have to queue!
The attraction is housed in the Visitor's/Welcome Centre on Table Rock so is extremely convenient and easy to get to. There is also a brilliant shop there selling a wealth of souvenirs at bargain prices with some sale items too!! There is also a variety of places to get food/drink and there's well maintained conveniences.
Once inside the Visitor's centre, you go up a small ramp and you will see a speciality sweet store with some amazing delights!! At the top of the ramp is another shop with different items on sale, again at very good prices (especially authentic and handmade clothing).
When you queue for the attraction, you will be given a max and a warning that you might get wet - my advice - TAKE THE MAC AS YOU WILL GET WET!! There isn't anywhere that you can leave your belongings so please bear that in mind with what you take in to this attraction (save your shopping for when you leave).
There is a 5-10 minute cartoon show which gives you an insight to what you are going to see and it is done brilliantly with humour yet being informative at the same time! After watching this, you are admitted in to a large room where you stand (but there are handrails in front of you), it doesn't matter where you stand but depending on where you decide will determine what 'weather' you experience!!
This is an extreme 4D experience giving you a 360 degree view of Niagara Falls with all of the sights, sounds and feelings of actually being there! If you would like to know a rough expectation of what you will experience, people on the left hand side get blasts of cold air, people on the right got snowed on and people at the back (like we were) got drowned!!!
This was one of the most memorable attractions that we did and worth every single penny - I think it's actually not advertised enough as we all enjoyed it so much we came out in hysterics with everyone talking excitedly about their favourite aspects of it - you will not be disappointed by this addition to the Niagara Falls attraction list!!
