Seibu Kogen Bus schedule

Hello all! I will be travelling to Manza Prince hotel on the 13 of december and I will probably take a train to Manza Kazawaguchi and from there, take the seibu kogen bus. I know that theres a shuttle bus to manza prince hotel but i wont be able to make it in time for the last shuttle. I would like to know the bus timings towards manza prince hotel from manza kazawaguchi on that day if anyone knows? i have tried looking online but the schedules are mostly outdated or not valid for the day that i will be heading over. btw i will reach manza kazawaguchi at approx 2.55 pm. will appreciate any help! thanks so much in advance.

Although the bus doesn't stop at the Manza Prince Hotel during winter, it is said that courtesy shuttle will be provided from the bus terminal to the hotel.
