Which ten hrs will you be there? There is a hotel fairly close by that could be of use to you.

This is the hotel used by UA for misconnects in years past when UA flew to Saipan and Guam from KIX. It used to be the Nakamachi Garden Palace in those days and yes I misconnected and stayed there at UA's expense. It was a family run business type hotel. Reasonable rates, dining room, bar and the baths are very relaxing! Look for my picture on the wall just as you enter the bar area. Enjoy
