It's weird that they list the limo bus from KIX but not from ITM. This site shows the bus from ITM also stopping at Kinetsu Uehommachi

We're going to book here as we need room for 1 night for 3 people and not allowed at Marriott. It's annoying how hard it can be to get 3 adults in 1 room in Japan. All other nights (Kyoto and Tokyo) will be in Airbnb so at least that will be easier. We'll see what we get for 1 night with 3 adults as Platinum but not until May 2018 when we go.
