So, Dubai's megaresort will allure tourists for a long time.

So, each chef is required to choose what kind of food and think about how they are cooked to stimulate athletes' appetite.
It won't be an easy stuff.

To compete with the hotels run by international hotel giants is difficult for the local hotel. And also, it will be much more difficult for it to maintain the position of the best hotel every year. Part of the reasons is that local hotels cannot serve discounting systems which are also acceptable at hotels worldwide. It means businessmen flying to international destinations frequently cannot get benefit at local hotels.
Those who intend to open small hotels in international cities will have to think about how to make difference between them and international hotels.

It's not only ineffective, but also dangerous for Pope to do that, if countries occupied by majority of fascists try to hurt him because of his mindset.

But, it would be necessary for Pope to enlighten people not to rush to war, while peace is maintained.
