If you buy your tickets online you can escape long line outside in the heat to get the gate.
Yes should also could buy them when you get there
You don't escape the heat by buying online because there is only one line. EVERYONE must pass a security checkpoint before they are allowed in to the front desk to buy tickets or pick up prepaid tickets. There is no skipping the line.
You can buy in advance or buy in there too! Only prob is if you buy it in there and line is long and hot outside you might be inconvenience. I'd say buy in advance just to skip the line for tickets if there's any.
It won't make a difference if u buy before or not because when you purchase the ticket or tickets they put a bracelet around your wrist.so you can go in and out that day.
