Cruise stop in Sanya/Hainan, Royal Caribbean International

Hi,

I'm a Finnish citizen about to embark on a cruise that departs from Hong Kong, and will have one stop in China: Sanya/Hainan. Based on the visa exemption rules, I should not need one if Royal Caribbean International qualifies for this: "organised by International Travel Agencies that have been set up and registered in Hainan Province".

Can anyone say whether Royal Caribbean is OK for this exemption?
