Hello, Hotel Keihan Asakusa ! :)
I would like to know whether your hotel is open for 24 hours ?
Given that we will arrive at Narita airport about 10:00pm in 2/18 ,after that, we might probably take the Tokyo Shuttle（東京シャトル）to Tokyo,and then, the subway to Asakusa.
Eventually,our arriving time might be around 11:30,so I was wondering whether it is too late to check in?
Thanks for your help!!!:)
