I have stayed at this property a couple of times and always have had a great time with none of the issues the review above mentions.
However, one of the issues with this resort property (and this may be a common practice at resort hotels, I am not in the industry so wouldn't know ) is that individual rooms are actually owned by investors. They receive a bank of free nights per year which they can use or give away. The room owner has a maintenance contract with the Hilton and whilst I have no knowledge of the workings of this contract you can see that theoretically there is no real incentive for Hilton to spend money on room repairs unless absolutely necessary and bank the maintenance income. The problem room in question may have had a succession of free-nighters who are perhaps less discerning as they have been gifted a room for a week or two. This allows the problems to build up over time.
I did look into this as an investment and the agent said that the return was around 12% per year as you get a cut of the room rate.
