It is suggested that you buy tickets online as they still have a limited number of people in the park. If you want to go during the week you will have no problem just arriving without a ticket purchased online. If you want to go on a weekend then it is better to buy online. It is also good to note that prices change depending on the day you are planning to go. During the week (Monday-Thursday) it is cheaper.
You can arrive without an appointment
One can come without an appointment! But the ticket price is a bit high per person.!
