Day trip package to Jozankei

I am intending to use the day trip package to Jozankei at a cost of 1800yen. The website shows :
Fare : Adult 1,800yen / Child　900yen
From Sapporo Sta.& Makomanai Sta.
Include a shuttle bus ticket and a bath ticket.

Is it a round trip ticket to/from Sapporo or just a one way ticket and i need to pay for the return ticket??

Please link the website next time:

It includes a round trip by bus.

Thanks for the reply.

For the bath ticket, I just need to show it to any of the listed hotel in order to enjoy the onsen?

Yes, that's right. Many places charge separately for towels, though.

Hi,

I was wondering. Can I buy the tickets from station e.g. on Monday, if I intend to use it tomorrow or later date.

Also. I notice the towel rental charges.
Can I bring my own towel and forego the towel charges?

Thank you

Yes, you can bring your own towels
