Can I bring food in the swimming pool of a five-star hotel?

Of course. Swimming pools and gyms in five-star hotels are usually welfare facilities for hotel guests. The swimming pool of a five-star hotel provides delicious snacks, fruits, cold drinks and so on. It's free, and there's no rule that guests can't bring food. Therefore, the swimming pool of a five-star hotel can bring food, but not some irritating food, such as stinky tofu and durian.
