It is not recommended to get off at Wuhan Station, which is quite far away, and there are not many trains from Shiyan to Wuhan.

If you get off at Hankou Station, you can have a good look around Hankou on the first day. There are many places to go shopping in Hankou, such as Hanzheng Street, Jianghan Road and Wanda. You can go to Jiqing Street for a midnight snack and visit Jiangtan at night. If you are interested, you can take a ferry to Wuchang and then stay near Simenkou at night. Get up early the next day and go to Hubu Lane early, and then you can get ready to leave for Happy Valley to have a good day. I suggest you arrive early, preferably around 9: , because it's a lot more serious. Play in Happy Valley until the afternoon. If it's still early, say two or three o'clock, then you can transfer to the provincial museum, which closes early. If you play in Happy Valley for a long time and it's getting late, you can go to Chuhe Hanjie or Optics Valley and stay there at night. On the third day, you can go to Yellow Crane Tower and Hubu Lane, and then it's close to Wuchang Station, so it's convenient to go back.

If you get off at Wuchang Station, you can go to Hubu Lane and Yellow Crane Tower first, then take the ferry to Hankou, and then you can stroll around Hankou the next day. In the afternoon or later, you can take the subway to Wuchang, just sit at the end of Optics Valley, and walk around Optics Valley at night. If you leave early in the afternoon, you can go to the provincial museum. On the third day, you can go to Happy Valley for a day. When you go back, you can choose Wuchang Station or Wuhan Station.

ps: I don't know when you will arrive in Wuhan, but I recommend it all day. You can make plans based on your own time, which will save a lot of time.

Regarding accommodation, if you want to be cheap and affordable, you can go to the group buying website. If you want to go to Wuhan on a holiday like May Day, I suggest you make a reservation in advance, and the house price will go up on such a big holiday. You can go to some travel websites to see if there are any hotels suitable for you, such as Ctrip and eLong.
