Many of them have never been out of Auckland and none have stayed at a plush hotel before. They love the beach, the hotel, the competition with 80 football teams, the amazing atmosphere at Blake Park - they just cannot stop smiling.
This sort of life-changing experience is the pay-off for Semple spending 12 months a year organising the event. It is what keeps her going.
"That situation where teachers go the extra mile to give kids an incredible experience just blows me away," she said. "It makes me think I am so lucky to have a job where you actually can make a difference in people's lives."
With about 10,000 visitors descending on the Western Bay this week, the accommodation providers fill a crucial role. Not only do they shelter the competitors, coaches and parents, but they are the first and last point of contact for the visitors.
Semple knows just how important their role is in making the Aims Games such a success.
"The other really cool thing is I have heard so many schools saying that the people at the places they are staying have been coming to watch their games. Everyone just gets drawn into it. It just has such a fantastic feel about it."
Semple is pleased to offer a new sport this year and has already organised yet another for 2015.
"We have added a 17th code this year in table tennis, which has gone extremely well," she said. "Next year we have got sailing, which will be awesome. It is an iconic Kiwi sport so it will be great to get that in and promote the Tauranga Harbour."
