We're travelling through Japan with 2 kids, 9 & 11, and didn't want the full-blown "all meals included top-end ryokan package" as that would've been wasted on the boys. We did want to experience staying in a ryokan, bathe in an onsen and hopefully see the snow monkeys, so chose the Koiishiya and don't regret the decision. Not only did we manage all our aims in less than 24-hours, when the monkeys only appeared just as we were leaving to walk back to Shiba Onsen I booked a taxi so we could stay an extra 25 mins ( having seen none for the first 90 mins), however it didn't work out and we ended up missing the train we'd planned to get back to Yudanaka ( a problem as we'd already booked seats on the two other trains to get us to Kyoto!). No problem to the staff though - they immediately offered to drive us, not to the local station, but one 20 mins away which allowed us to get back on our plan, with no expectation of payment - truly fantastic service. We really enjoyed our visit to beautiful Shibu Onsen and the Koishiya experience was a big part of that. It's a great way to experience staying in a ryokan without breaking the bank, whilst having a coffee shop and restaurant within your hotel and access to a couple of lovely onsen - we'd definitely recommend it.
