Wow. Just such a great experience all round. We arrived around noon on a sunny winter day, the skies were clear and there were no lines at all, we just bought a ticket and went on up. Cool elevator experience, then stepping out onto the glass floors and the magnificent views was just breathtaking. It is so cleverly designed with so much to see from inside so when it's cold/windy you don't need to go out to get the best vantage point. The balloon room was fun, who knows why it's there but it makes everyone smile and feel good. We had a drink at the bar as well and sat and enjoyed the stunning views. Being able to go out on the ledge with the glass floor was fabulous as well, and truly special to look down at the city from the floor and of course have your 30 seconds to grab your selfies as well. I don't know how you could be disappointed in this place, I would recommend it to everyone.
