The descriptions of amed sound really extra cool, we're planning to give it a try when we go to Bali in June. Just wondering though - we've an 8-year old and a 11-year old who can both swim, but not that well, so snorkelling close to shore sounds good. Would there be a problem though getting the kids proper equipment ( eg life jackets!) to go snorkelling with? Do we need to bring anything with us? someone on this forum wrote about reef shoes, but these don't seem to be easily available in Urban Singapore where we live!
