Well, which city of Hubei Province would like to travel? Wuhan, the capital city of Hubei? Well, the cost of this city is moderate that I have stay there for a whole last summer, and just cost 20yuan for dinner and 50yuan for the ticke to visit the Yellow Crane Tower. Both of the taxi and the city bus are cheap, too. Well, except of hotel, I think 1000 to 1500 is enough per person for five days. As for the hotel, you have many choices of those economical hostels. 200 to 300yuan is enough per night. See those noted ones like Home Inn and Jinjiang Inn.
