I expect they are busy ordering in extra champagne and beer at the Kingsgate Hotel.
Mind, I suspect the bar staff there might be feeling a little nervous. The reason? Aaron Gilmore is in town.
The Heritage Hotel in Hanmer Springs is still reeling after the National Party MP attended a shindig down there last week and ended up with his face splashed all over the front pages and TV news bulletins.
The story goes that copious quantities of alcohol made Mr Gilmore "boisterous"; that he was whistling at the waiters and clicking his fingers; that things turned ugly when he was refused more drink.
The occasion was National's regional conference and, funnily enough, that's exactly what brings him to Wanganui this week - the party's lower North Island regional conference. Being a list MP and therefore attached to no particular geographical constituency, Mr Gilmore has no excuse for not attending any of these get-togethers. In fact, as a party animal, I imagine he regards attendance as compulsory.
