I have just returned from my third year at The Royal Cancun and the renovations are well under way. On our last day there was scaffolding in the lobby and they are doing renovations around the pool.
I spoke with a couple of friends that work in the hotel, Astrid and Luis but they have not been told of any changes other than it will become a Hyatt. All the staff were very eager to find out what I knew but unfortunately it's as little as they do. In my opinion it can only be for the better as parts of the hotel are beginning to look tired. If they change all the staff however I will not return as they make the hotel what it is!
If anyone has any questions, let me know.
