Yes, we were with Ian. You mean where you spend the night in the caves? The 'honeymoon' tour? Was told some amazing stories about this one, I'd highly recommend it. Tony, who does the parasailing trip off Fido's dock, said it was the most amazing thing he has ever done. And the list of stuff he has done includes some pretty remarkable things!
They pack in everything one might need, bed, candles, food, feathers (tee hee), and there is a river you can swim in in the cave where you spend the night. sounds rad.
