First, it can be a "sailing hotel in Dubai", which is luxurious and made of 40 tons of gold. It is the first 7-star hotel in the world (but now it has 8 stars, which is also in Dubai). It is a 56-story sailboat-shaped tower building built on an artificial island by the sea. This one I made last time was very successful, hehe.
Secondly, you can try the theme of the advertisement, which many people do, because the pictures are easier to find and more interesting. You can discuss the advantages and disadvantages of advertising.
Thirdly, the underwater restaurant, as its name implies, is a restaurant built on the bottom of the sea, which is more eye-catching.
