I brought my own mask, snorkle, and fins. My fins fit perfectly in my zipped front compartment of my suitcase (that NOTHING else seems to fit in) and didn't take up any space for my clothes. I'm nearsighted and have prescription lenses in my mask so I like to bring my own. There are plenty of places you can rent tho- ask around. Have fun! Take lots of pictures and be sure to post them on this board (Photo forum).
