Toyoko Inn Himeji Station Shinkansen Minami in Himeji

I entered the age of my child and it was displayed that sharing a bed was free, so I made a reservation, but after arriving at the hotel on the day of my stay, I was told that children could only stay at the adult rate. If there was a special reason why the child rate was not applied, they should have confirmed it at the time of booking and contacted me in advance, but the hotel staff should have known that it was impossible to find a hotel that could be booked on the day after arriving at the hotel while making an exhausted child wait. Moreover, even if I was lucky to find another hotel, they said that if I did not stay at Toyoko Inn, I would have to cancel on the day and be charged 100% of the accommodation fee, which was essentially a threat. Is it okay to charge an extra fee using such a fraudulent method? In the hotel room, my child was bitten by a tick and was itchy and painful, and I couldn't sleep, and at breakfast, an elderly male guest was pushing my child from behind in the line, but no one warned him, so in the end, I had a bad experience at Toyoko Inn Himeji and it was a very sad stay. It's a shame.
