We'd been pre-warned that Robinson Crusoe was like "Disneyland in Fiji" ..... ummm, not quite, but an entertaining day trip from Nadi.
Lots of things for kids - & adults - to enjoy. A snorkel trip (bad when we went out - poor visibility & lots of dead coral, but the one sea snake was a highlight), cannibals, fire walking, fire throwing, Pacific dancing, a nesting turtle & a yummy lovo lunch.
Staff weren't "jaded" & seemed to enjoy what must be a very repetitive job.
Downside is waiting around in the minibus in Nadi as different groups joined the group. But that's part of the "Disneyland in Fiji" experience.
