Those prices are okay for us to do our own thing but if a few want to get together and transfer it would be even more economical. Much easier than the train that is for sure.
We are staying in the airport hotel in the terminal the night before embarkation. We will use this service and pay a little extra for a quick tour of Sapporo and Otaru before arriving at the ship. Wont see much but better than nothing. I doubt anyone else is coming in as late as we are but happy to share if anyone else is staying at the airport hotel.
