sorry yes the air is free all day.
i recommend you arrive at the site about 8.50, we will then set up and start playing around 9.30.
stop for lunch around 12.30/1ish for about 20 mins, then play until about 4.00/4.30
we try our best to play as many games as we can during the day, around 15 is not uncommon.
