If I was to get here on a Friday at 9am, how likely am I to get the first come first serve sections? Should I go on Thursday instead?

It depends on the weekend. I would try to go Thursday.

Wed thursday would be best for the come first serve

Thursday wiuld better but ita still chancing it. Sunday would be best.

Thank you for your quick response:) we’re not planning to go on a holiday weekend so I hope we get the place we want ☺️
