I visited Okinawa Prefecture at the end of 2019 and the beginning of 2020 with my family including an infant. We stayed in a hotel for 3 nights. The hotel is Okinawa NaHaNa Hotel & Spa. Our experience there was very nice so we recommend families including infants to stay there.
When I planned to visit Okinawa, I looked for a hotel we could stay with an infant with Expedia. I am a gold member of Expedia so I looked for an Expedia VIP hotel then I decided and booked the staying plan including breakfast.
The hotel is located between Asahibashi Station and Kencho(The head office of Okinawa Prefecture)-mae Station of Yui-rail(monorail). It takes about 10 minutes from each station to the hotel on foot.
We stayed in a twin room. The room was not so narrow and enough to stay for 3 of us. The room was clean and had ordinary amenities. There is a convenience store(Family Mart) in the next building.
The hotel has a lounge on the 1st floor. You can use the lounge anytime before 8 pm. You can get some kinds of drink like coffee and Okinawa style drink and Okinawa style snacks free of charge. You can take a rest there.
A breakfast restaurant is located on the 2nd floor. The restaurant is buffet style. We can have Western style, Japanese Style and Okinawa Style menus there. Infants can eat few kinks of food but it is easy to find the food infants can eat because there are many kinds of menus. Also, you can try Okinawa dishes there.
If you planning to visit Naha City, Okinawa with or without an infant, I recommend you stay in Okinawa NaHaNa Hotel & Spa.
