How do I get to Hezhou?

I'm planning to go to Guposhan this weekend, leaving from Guilin city.
What is the best way to reach this place? Bus Guilin-Hezhou, then to Guposhan right? How long? How much? What time (shedule for round trip)?
What's the best way to do: staying in the hostel overnight or do the trip in one day?
If I have to stay in the hotel, should I book before going or do you think there will still be rooms available (single person)? How much then?
How much is the entrance fees of the Forest park?
...Sorry for so many questions...I couldn't find all the informations on their website and my Chinese isn't that good to ask them on the phone ;).
Thank you so much in advance for the informations! Your Q & A part is just awesome!!
