"I advertised in Wellington some time ago for this weekend and that's how I filled our place up. Other motels have been ringing me to see if we've got space. If anyone is coming here for the athletics for the one night I'd say good luck to them finding a place to stay," Mr Wheeler said.
And it's a similar story at the Grand Hotel where a spokesperson said just about all the guests were coming here for the Vintage weekend.
Anybody caught out and in need of accomodation can try Top 10 Holiday park in Aramoho which had a few vacancies late yesterday.
