翻译一段文字，尽量简洁

据说全世界排名前30位的超级酒店中有20大在拉斯维加斯；全世界排名前十位的超级酒店中有7位在拉斯维加斯。拉斯维加斯酒店有两个特色，第一都是酒店和赌场相结合；第二酒店的外形都成一种类似“人”字的造型。有意思的是，在发给媒体的说明信中还特地强调，从MGM的大堂走到会议中心大约需要15分钟，请各位注意安排时间，可见MGM这座世界第一大酒店究竟有多大。

Said that the world's top 30 super, 20 large hotels in Las Vegas; the world's top ten super hotel has 7 in Las Vegas. Las Vegas hotel has two special features, are the first combination hotel and casino; second into a hotel's appearance is similar to the "human" character modeling. It is interesting that the letter sent to the media statement also wished to emphasize, from the MGM Conference Center lobby walk takes about 15 minutes, please note that arrange a time, we can see the world's first Grand Hotel MGM this how much big.
