No sir. You can just walk up and walk in. No reservations needed.
Nope. U can take pictures inside the gift shop also
None needed!
No reservations are needed NV locals do get a discount. You can take pics outside and in the lobby but not on the tour.
No
You don't have to make a reservation, but you can if you're worried about having to wait for a tour.
It looks as though you may save money online. I saw someone who paid less than me. I bought them at the door and they were $44.00 all in for each.
No, you do not. However if you do not buy tickets online for the day you are going, you take the chance they might sell out.
