Can i buy the tickets at the park for jurasticdinosaurs

Yes

Just make sure you buy them and get for what ever it's your tryin to go to

I would think so but I'd check their website.

I haven't heard of that at all , if the event will take place there it makes sense but I'd go in advance if i were u which is wat i usually do go at least 30,40 min in advance to find out
