I did this November 2008. It was very fun, exciting. After safety briefing you aare led out of the bay to the ocean. You travel with 2 guides, or at least we did, one in front and one follows. you will travel to an area where you can see the docked cruise ships and then have time to snorkel if you wish. The photos that have been mentioned are 8/11 and come in a folder and certificate of achievement showing your achievement "I rode a rhino"
. They accept cash, credit cards. If you really enjoyed your Safari and guides a tip is appreciated. When I booked this through RCC they charged per person. Through Princess they charge per boat.
