The one element they cannot influence is the weather and even this has been largely co-operative for the annual family day out in Brighton over the past three decades.
Some rain has been forecast by the MetService for Sunday, but gala co-organiser Colin Weatherall had a slightly different take yesterday.
"It looks like it’s going to be mild, maybe the odd shower.
"That’s about as brave as I’m going to be.
"That’s the one thing I can’t pull the strings on."
In any case, a few spots of rain at Brighton Domain would not be enough to force cancellation of an event expected to again attract thousands of people.
Colin’s son, co-organiser Scott, said the gala had never had to be cancelled because of weather.
Wind had historically caused some trouble with gazebos, but rain was not a massive issue and the sun tended to show up at some point, he said.
The Weatherall family leads a large logistical operation to prepare for the event and dozens of volunteers pitch in.
Last year’s gala attracted more than 12,000 people.
About 200 stalls are booked, including about 30 food vendors, for the 29th event.
The day will again feature a variety of amusement rides and Helicopters Otago is providing scenic flights.
Other experiences range from music to a sauna.
"We love the Brighton community ... and for us it’s an opportunity to share with others, I guess, our little piece of paradise," Scott said.
"But also it provides an opportunity for community groups to raise funds, to raise awareness."
A low-cost barbecue or two will also be run.
Scott credited his father with leading the organisational efforts and his mother, Ann, for work behind the scenes.
There is free admission to the gala grounds.
Donations are accepted at the gate for the Brighton Surf Lifesaving Club.
"It’s absolutely free entry, but if people feel that they would like to make a donation, it’s absolutely awesome," Scott said.
The day was focused on bringing people together and providing an opportunity for them to reconnect.
Colin said it was a fun day for the whole family.
Money from the Lotteries Grants Board, Dunedin City Council events fund and Aotearoa Gaming Trust helped to cover costs.
The gates are due to open at 10am.
