We were staying in Diploma for last 3 years, but our last stay in May 2019 (after it became Hilton hotel) was a disappointment.
First, the hotel now lost some details that luxury hotel used to have before and a lot of small details disappeared from a bathroom and from a room (bathroom cap, hair conditioner, sleepers, night gowns, glasses for tear/wine, wine opener, tea bags,..).
Yes, you can call and ask to bring it in and they will bring it, but it takes too much time and plus they do not bring all you ask and you need to call them again and again what is a frustration for 3 day stay. You also do not have it when you need it and to wait for 1 hour or more to get it is too frustrating.
In addition, we had a serious problem with their customer service which shows that they do not care about their guests. They charge $22 per day for using umbrella on a beach and we use it for 1 day and have a receipt. They charged us twice $44 for this 1 day and I did not notice it during a check out, but called them in 1 hour after I left hotel asking to refund $22. It took me to call them at least 5 times during next 2 weeks about this refund and spend a lot of time. I wanted to do this just to make them do a right thing and to check how they are handling beach service, but it was a wasting of a lot of time. At the end, they refunded only $14.12 (why this amount???) and I gave up.
During my many conversation with their customer service, I could understand how they DO NOT CARE about you and your problem.
I would not stay in this hotel anymore and will not recommend other people to do so - the price and a level of services do not match.
