Under the perfect conditions playing tennis in the winter? Thanks to the inflatable sports balloon facility of Foundation Wintertennis Franeker it is possible. ICIT built a website for the foundation and developed a unique reservation system. Through the reservation system you can easily rent one of the tennis courts and pay immediately with IDeal. But this is not the only thing, if a court is reserved, the heating system, lighting and access registration are automatically controlled.
Soon you will find an in-depth case-study about the tennis balloon here.
