Yes, there are 6-star and 7-star hotels -- but only unofficially. The maximum official rating recognized globally is 5-star.

Dubai's Burj Al Arab was the first to be described as a 7-star hotel, and several more have followed since. There are just a handful of hotels in the world that have been loosely classed as 6-star or 7-star, and its easy to see why -- they go all out for luxury, opulence and such unique extravagances that 5-star doesn't suffice. The term was coined as a superlative rather than an actual rating. It's meant to signify the extreme glitz that takes these hotels over the 5-star mark, so they usually skip 6 and sit at 7-stars.

At each one, privacy is paramount and you're treated like royalty. Think helicopter transfers, 24-hour butler service, personal attendants, gold-plate everywhere and a fleet of luxury cars. Maybe even yachts!

A hotel chain refers to several hotels operating under the same umbrella brand.

You know what you're getting when you stay at a luxury hotel chain. No matter where you are in the world, the brand stays true to form. Guests can comfortably expect a familiar experience at each property. As the large hotel chains can be found in many cities, they are a popular choice for many travellers.

Some of the most well-known luxury hotel chains are Hilton, Four Seasons, Marriot, Starwood, Ritz-Carlton, Intercontinental, Hyatt, Wydnham and Shangri-La.

Some boutiques are classed as luxury hotels, while others are not. It depends on the standard of the accommodation.

Many boutiques are designed to cater for high-end customers, who want to stay in an independent hotel that offer the 4-star or 5-star amenities they would expect in a luxury chain hotel. Where the d`cor, amenities and standard of service is akin to that of an upmarket hotel, a boutique can legitimately be classed as luxury.

This is very hotel-dependent as there isn't a strict benchmark. One hotel may use "superior" where another might use "deluxe" for the same definition of features.

To some extent it also depends what you consider "better", as the rooms might be identical with the only difference being lower vs higher floors, or garden vs street view. When you're searching Expedia for your accommodation, take a moment to scroll through each room's description and pictures to compare and find the best option for you.
