How to get from Kii-Katsuura to Koya san

On 7th of November I like to travel from Kii-Katsuura to Koya-san. Accorting to the Hyperdia site, it wil take about 8 hours by train. I also found a bus connection that goes from Kii-Tanabe to Koya-san with a tranfer at Gomadansan. That will take about 5.5 hours (including the train from Kii-Katsuura to Kii-Tanabe)
My questions is: will those busses wait on each other at Gomadansan because there is only 1 bus?
Or is there an other way to get to Koya-san al together.

Thanks you for the answer(s)
Greeting Yvette

I think Kuroshio Express is still available in this Nov as they sell the ticket effective by Mar 31 2013. ^ ^

A third option would be to travel by via Gojo. Bus timetables are here:

As for the Kuroshio limited express train, it runs everyday around the year. It will not stop running this autumn.
