We are travelling back from Hiroshima en route to Kansai International airport and require accommodation for one night. We need to be at the airport at 1800hrs and are thinking of doing a day trip to Mt Koyasan. Does any one have any suggestions where 4 people could stay this final night and how best to get to Mt Koyasan, if this is possible to do in a day. Any other suggestions would be appreciated. Thanks.
