The tour sellers in Yangshou will sell you tickets regardless of the desires of the raft operators. In our case we bought 5 tickets for one raft. We arrived at the river, got on a raft, took our seats, pushed off and then all of the sudden the raft driver said he could only take four of us because of the "River Police". He asked for another 100RMB for a 2nd raft. We refused and then he followed us as we walked to other raft operators and he told them NOT to let us on their rafts. So there is really in my mind a widespread scam going on to increase their profits. We refused to pay and went back to Yangshuo and took a ride very close to the city which we absolutely loved. We lost our 100RMB, but have the satisfaction that the corrupt raft operators up river didn't get any of our money.
