I originally booked into a deluxe room at the Royal Beach and arrived late the first night. The deluxe rooms (and I assume superior as well) are in the older wing (overlooks another hotel - to the left of the reception if you're facing the beach) and I was booked on the 3rd level. The room facilities were a bit tired for the price you were paying $170/n and the air-conditioning was not really keeping the room cool.
I contacted the reception the next day and said I wasn't really happy and whether they could find something better, (it's a lot to pay if its not the same standard you expect from Accor) and they upgraded me to a grand deluxe room.
This is what I expected having stayed in many Mercure, Sofitel etc chains of the Accor group around the globe. The aircon was great, room was better and closer to being fair value for the price.
Grand Deluxe or better and this will be a great experience for you.
