2 day is enough to tour around Kanas reserve for photographer?

Because my team has some photographers ,so they need the time to take photos

One more question, If we want to get the Cruise ship in the Kanas lake ,the time should be increase to 3 or 4 day travel all attraction in Kanas reserve? (not include Hemu village)

Please tell us the fact & data, it's fine if only 2 or 3 day in Kanas reserve is enough
Thanks
