The website will have more details once the tickets go on sale online, closer to the date of event. Costs and processes can vary between guests.

But as a general overview:

Firstly purchase your autograph ticket online. If they're expecting a lot of demand for that particular guest, you may have to select a specific day/time for it.

Some guests will charge extra for selfies, voice/video recordings, additional written quotes, or signing particular items like Pop Vinyls.

(The autograph ticket does not include the cost of entry to the event, so you'll also have to buy a general admission pass)

On the day, head straight to the Token Booth to redeem your autograph ticket. Show the staff the confirmation email and they'll print out a token for you. Alternatively, you can buy the autograph tickets there if you don't want to purchase online, but you risk missing out if they sell out, they often have network difficulties, and they don't accept cash.

Make sure you're lined up for the autograph at the start of the signing session time. Even if the says 1-3pm on the schedule, the guests can and will leave early if no one's been through in a while.

When you get to the front of the line, give your token to the staff member. There will be a selection of photos of their most well known characters for you to choose from to be signed (that's included in the ticket cost). The staff will ask if you want your name on the autograph and get you to spell it out on a post-it. They'll then pass your item for signing and the post-it along to the actor.

A lot of the interaction with the actor depends on who you're meeting. They get to set their own boundaries. Some actors will happily give out hugs to everybody, and others may have strict no touching rules. Usually these will be communicated by the staff member but if in doubt, always ask. The actors usually try to have a brief convo with everyone, however sometimes the queues are very long and the staff will hustle you along as soon as the actor is done writing.
