I agree with that. I have two reasons. First, a lot of people feel burdened by paying the entrance fee. So, if they don’t pay a fee, they visit there more quickly. Second, children can increase opportunities to learn environments. No matter how they do not have enough money, they can learn it quickly and significantly increase their knowledge. Therefore I agree with entering the museum for a free fee, and I believe it will be an excellent opportunity to increase customers. feel dullで、かったるく感じると言いたかったのでしょうか？まあ、それでもいいのかと思いますが、他の表現にしておきました。 その他細かい修正をしましたが、意味は変えてません。
