Is the accommodation a hotel or an ordinary hotel? Hotels should not be too expensive, but pay attention to property safety. It is suggested that the accommodation in the business hotel in the city center should not be too expensive, and it is also convenient to take the 13 road to the Giant Buddha. If you only go to the Giant Buddha, it will be done in one day, and you can stay for one night at most, which is less than 100 yuan. If you are a student, you can also go to the Teachers College. There is a temporary rental house near the Institute of Science and Technology.
There is no need to book tickets in advance. There are quite a lot of trains every day, but if May Day comes, you can consider booking tickets.
In short, if you want to visit the Giant Buddha, you don't need to live near Grand Central Station. Just find a place to live in the city. It's not far from 13 scenic spot and 6 bus stop, so you can make time.
Have a nice trip ~
