Hi, planning to be at Guilin Int. Airport on 11.00 am on April 2015

I've read somewhere (Answered by Mrs. Jenny from China) that cruises from Millstone Hill Dockan or from Zhujiang Dock to Yangshuo depart at 9.30am 10am and 2pm. Can anybody-preferably- "travelchinaguide.com" represantative confirm especially the last one? Thank you
