Round about now, the helicopters are whirring over Waterville, depositing the first of some 85 father-and-son teams for a unique golfing event.
One of the most prestigious - and expensive - social events in the international golf calendar, it's the 17th annual World Invitational Father and son tournament at Waterville Golf Club.
Rated in the Irish top five courses, Waterville, in south Kerry, is also in the world's top 20. To participate in this tournament, families need to be pretty high in any wealth league you care to mention.
The entry fee begins at €1,815 per person, and goes up to €3,000, depending on whether participants choose to stay at the Waterville Lodge or the more luxurious Waterville House.
Tiger Woods, Mark O'Meara and Nick Faldo all play Waterville at least once a year. The course, through sand dunes and the spectacular scenery of Ballinskelligs Bay, will see some of the biggest names of the Irish rich list hit the manicured greens. A third of the two-man teams will arrive from the US; Canada and Britain are well represented as is Ireland, and a team will also arrive from Australia.
Despite the strong presence from the US, only two father-son teams from there have won the tournament - last year's winners Aidan and Sam Browne, who are back to defend their title.
The Irish have had better luck. Dermot Desmond is the only father to have won the tournament with each of his three sons, Brett, Ross and Derry.
Desmond and Ross are scheduled to play again this year as is JP Magnier and his son Tom, and Patrick Guilbaud and his son Charles. Other well-known names to arrive tomorrow include JP McManus and his son John, and Paschal Taggart and his son Shane.
The tournament begins with a practice round which will be followed by three days of play.
After the first two days there will be a 36-hole cut and the top 24 teams will compete on the final day, with a plate competition for the remaining teams.
There is also a trophy for the best overseas team score over 54 holes.
The tournament is about good golf - Aidan Browne last year played off a handicap of eight and his son Sam played off 14 - and, according to organisers Carr Golf, it is also very much about giving father and son a chance to be together. "It provides a fantastic opportunity for father and son to spend time to compete together and to meet friends, old and new."
As well as golf there is a hectic social scene with barbecues, lunches, and a gala dinner and prize-giving evening at the Waterville Lake on Saturday.
Tomorrow sees a long drive competition followed by fireworks display at the Waterville Lake Hotel where much of the socialising will be done.
So popular is the event there is a long waiting list. But priority is given to past participants - with healthy bank balances.
