I bought the group tickets of 15 people but need to add 1 more ticket can I add extra tickets after I already purchased the first 15?

Either call them or you can do that at the ticket booth.

Hello! No you can't do that, it doesn't let you... My group and I purchased more than 15, but after that check out, you can't, the same day I had to purchase one ticket separately. So when you have a group, you can purchase more than 15 tickets, no more than 50, everything has to add the same time, you checked out... Hopefully my answer help! Well if you have any more questions about it, call customer service 👍🏻 or send an email, have a great one
