loop bus from Hotaka to Daio Wasabi farm

i have 4 adults and a 3yr old child. We intend to reach Hotaka Station at around 12noon. Do you have any direction to the bus-stop for the loop-bus service to Daio Wasabi farm?

When is the last bus returning from Daio Wasabi farm to Hotaka station?

If i decide to take a taxi, will it be easy to get a taxi from Daio Wasabi farm to Hotaka Station? Will taxi allow 4 adults a a 3yr old child? is there a larger size taxi?

I will be reaching Hotaka Station on 13 June, Saturday.

thanks
