“Tour molto bello, e organizzato molto bene. Ptelievo kn hotel puntuale, il furgoncino era però molto sgangherato. Check in al porto veloce e molto ben organizzato. Barca veloce molto bella, con molti posti all'aperto a prua. Snorkeling piuttosto deludente, poca visibilità e niente coralli, solo rocce. Le soste sulle due isole molto belle, bagni in un mare spettacolare. Pranzo ok, grazie per aver preparato due box di cibo vegetariano per noi, non era un granchè, ma abbiamo apprezzato il gesto. Frutta in abbondanza a meranda, e acqua fresca a volontà sulla barca. Esoerienza nella grotta smeraldo molto suggestiva, la guida è stata molto attenta a trainare il gruppo al buio.…”
