I am interested in booking a private onsen for an hour or two in an upcoming trip to japan, likely Solaniwa. However, I noticed that it said family (married) only when it comes to booking a private onsen, would they check my partner and I's ID or anything to make sure we are married? I don't want to book it and then arrive there and be told that we aren't allowed (and possibly not get refunded). Thank you!
