can I get tickets for a particular time and day?

Try online. But there $13.00 at the gate

Tickets were $25 for me and $10 for my child. I didn't see anything that indicated that people were allowed in by appointment.

It was $15 per person when we went last sunday.but yes you can get them for a certain time!

Yes you can either get them at the gate or check out Groupon to see if they have any specials going on tickets as well

You can directly get the tickets at the gate. Usually the wait time never more than 30 minutes. There are many places to visit nearby to skyview, so 30 minutes just passes by very quick.
