Depending on the tour, tickets start at $18 and go up. Recommend booking in advance as there is limited space and some tour times do sell out. Also, evening is better so that you can see the signs lit.
Tickets are $18 plus. Can be bought online and reserve a time there. Recommended to do night but all tours are great.
I bought my tickets at the desk when I showed up. So online or in person both work for getting tickets. Evening is the way to go...the place is awesome once all the lights are on and you can see them.
I agree with Erin it all depends on the time and if you want a tour guide.
