Not really good according to my experience. The seats on the boat are not fixed according to your tickets, which means that you have to occupy your seat by yourself. Sometimes you have to rely on your luck. Besides, the washroom is public. So you can not expect a lot from that boat. Apart from the boat condition, the scenery of Erhai park is undoubtedly charming.

You organizer do not really understanding Yunnan,it is somehow a shame for you,why not rent a private boat on the lake,you can boat to Wase or Shuanglang traditional Bai village,what you said is follow the Chinese regular tour,so I am sure you are not very professional.
