Forbes has been providing reviews and ratings of elite hotels, spas, and restaurants since 1958. To preserve the integrity of their ratings, they do not notify an establishment that they are being reviewed. Instead, they covertly send out an investigator and, for a hotel, book two nights and three days. Over that time period, the investigator rates the establishment on over 500 different objective qualities. In order for a hotel to receive their highest regard, a five-star rating, the service must be flawless. In these types of establishments, the staff provides service before the guest even requests it and the amenities are truly luxurious. Forbes just released their 2015 list and only two major gambling cities had hotels which received five-star ratings- Las Vegas and Macau. Here’s a look at which places made the list, and also what they did to get themselves there. Forbes Five-Star Hotels in Las Vegas ARIA Sky Suites- The ARIA Resort and Casino is a sleek and modern full entertainment complex, topped off with numerous green technologies. Guests can visit the casino, see entertainment like Cirque du Soleil, visit the spa, swim, or even play golf. Encore Tower Suites - The Encore Tower Suites is on the same property as the Encore at Wynn Las Vegas, but it’s more posh and has a private entrance. It affords every possible extravagant amenity, such as a spa, golf, dining, a fitness center and gaming, plus it has massage tables in the rooms. Mandarin Oriental, Las Vegas - Although the Mandarin Oriental is not a gaming complex, it’s still near the action. Guests are treated to state-of-the-art entertainment centers as well as pass-through valet closets, so that staff doesn’t disturb their slumber while collecting laundry. Skylofts at MGM Grand - The top two floors of the MGM Grand are devoted to a high-class boutique hotel referred to as the Skylofts. Rooms come with all sorts of perks, technology, and gadgetry, but one of the biggest perks is the personal butler who is assigned to each room, providing around-the-clock service. Wynn Tower Suites - Tucked away from the hustle and bustle of the casino, the Tower Suites feel more like apartments than a hotel. That is, unless you consider the Ferrari dealership, personal shoppers, and staff at your beck and call.

They have an indoor infinity pool, provide in-room babysitting services, and will even monogram your complementary robe if you like.

However, it’s still a high-class establishment with exquisite design and amazing service. Crown Towers Macau - As part of Cotai’s City of Dream, the Crown towers provide access to gaming, live shows, a Forbes five-star spa, fine dining, and swimming. Despite this, the hotel owes much of it’s five-star rating to its gorgeous contemporary Asian design and impeccable service.

The rooms havemassive flat-screen TVs, views of the beautiful Nam Van Lake, and 24-hour butler service, among other things.

There is also fine dining, an upscale spa, gorgeous pool, and high-end shops.

Rooms are loaded with technology, easy controls, end even have surround sound. They also include walk-in closets, yoga mats, and have an espresso maker in the room. Wynn Macau - Everyone talks about how service should be at a five-star hotel, but the Wynn Macau really outdoes itself. Staff will literally deliver sunblock on a silver tray to guests at the pool and will hand out warm towels if the air becomes chilly. If a guest climbs into bed and forgets to close the drapes or shut off a light, there is a control pad beside them so they don’t need to get up. Of course, there are luxury shops and exquisite restaurants, plus easy access to the casino.
