“A good day out. Unfortunately the Emerald Cave which promised to be the highlight (based on others' reviews) was packed full of school trips and other tourists; which the tour company cannot control so is not their fault. When entering and exiting the cave there was so many people swimming through that you were constantly being kicked and at risk of being pushed under as rude individuals did what they wanted, rather than wait patiently - feeding this back just to help prepare other tourists for what to expect.

“Liian kiire joka paikassa ja liikaa ihmisiä. Opas epäselvästi kertoi ajan paikoissa. Snorglaus paikkassa ei mitään katsottavaa ja ihmisiä todellakin liian paljon. Vieri vieressä kymmeniä ihmisiä pienellä alueelle . Ja vielä opas unohti laskea porukat kun lähdettiin luola uinilta ja yksi asiakas jäi matkasta. kuski huomasi virheen ja äkkikäännös takaisin luolille. Mies löytyi luolien edestä ja onneksi oli pelastusliivit päällä, mutta paikalla oli enään kaksi pitkähäntävenettä. Todella huonoa asiakaspalvelua.”
