Beware of this website...
Just this morning, Nov. 16, 2016, two tourists arrived at the coron terminal port and presented an email and confirmation of boat travel from coronferry.com coron to el nido. They paid online at coronferry.com using their credit card knowing later that the website is not connected or did'nt made contact/reservation with the montenegro shipping lines (the ferry going to el nido and vice versa). At the end, they paid again for the tickets amounting to 1,760 pesos each.
Again, please don't make transaction at coronferry.com. it is a confirmed fake fraud website.
