As for the best times to come, early morning is usually quite quiet upto 1000, when it starts to get busier with the peak times probably between 1100 and 1300 local. Friday its steady all day, never quiet, but not as busy as Saturday morning.
Departures are busiest around 3-5pm, after that fairly quiet, particularly on Sunday.
As Philip said, arriving on the grass is easiest, with less traffic and very few people getting it wrong. But the hard runway arrival is also straightforward if you have read the AIC and know what you are doing.
see you there, lets hope the weather is as good as last year!
