dewa Sanzan

hi
in Mid Sept I will be visiting the Dewa Sanzan.
as I am departing from Takahata in the morning of 12 Sept I will only arrive at Tsuruoka in mid day. I am thinking of staying a night at Tsuruoka first.
then next day take a early bus to Mt Haguro. I want to hike there and stay overnight at the Saikan..
I am taking the public bus. but there does not seem to have a bus from Mt Haguro to Mt Gassan,. on a week day ( I went to the Shonai Kotsu website).
I also want to visit the Yudono san as well.

do you have nay suggestions?

much appreciated.
