Tickets for BD Nationals (spectator)

[KimYoung]

I am looking at buying tickets online for the nationals on the Sunday. There are tickets for the grandstand seats and adult tickets. Do I need to buy both if I want to sit down?

Probably a really silly question, but I have only been on a week day before.

Many thanks

The Grandstand seats are covered & offer a better view. There has been an uncovered seating area before which is free, but view is more restricted.
