Advise on Barregarrow

On one of the race days this year we would like to watch from Barregarrow.
We travel by bus.
Does anyone have some advise about watching here?
It looks there is not a lot of space for spectators and mostly packed.
Do we have to be there really early? Or better skip it, considering or travel limitation?

Thanks for your help
