I will be in Guilin from 8th June to 11th June'2013. I read it rains heavily in June. We are a family coming to guilin for Li River Cruise. I would like to know whether it operates in heavy rain also ? Is it safe in June to take Li River Cruize? please advise the appropriate clothes to carry and shoes. Also tell me the footwear to suit the season? Are there any vegetarian hotels????
