I stayed at IC Manza beach in this February. As I was alone, I went to the hotel by a limousine bus that took 90 mins (1,830yen) from the Naha airport. As a RA, the hotel offered the room upgrade to the corner suite, fruit plate, mini-bar free, and welcome amenity (small purse). Unfortunately I was not given the lounge access, and offered the lounge access by 2,000yen/night. I think that breakfast is complimentay for all guests and it is possible to use for lunch. There is Onsen on the first floor that every guest can use for free.
