You can look at it all you want for no charge.
I went after 6 Pm and it was free.
Right now for the Chill ice event it's $35 for adults and $25 for children.
We went after the main gate closed and got in for free. I am not sure about prices ...
And if you stay on the boat the tour is free the sea the whole ship. But it varies with the tour tour guide or without but it's a lot of fun to go without the tour guide. To explore the ship by yourself
$33 for adults, and the tour guide is great. There is quite a bit of history behind the Queen Mary that I wasn't aware of, all in all, I recommend a tour anytime of the year. Definitely worth the trip.
