Deep sea fishing in Mexico

[Oilers]

I am heading to Cancun in a few days and I would like to try deep sea fishing while I am down there. I have never done it so I wonder if some of you have tried it to give me some feedback on your experience. Do you like it? Which company did you go with? Did you get to keep the fish you caught and what did you do with it?
Last time I was down there, I went to Xelha and my kids loved the place. Is there something else down suited for kids? Mine are 6 and 4 years old. Thanks everyone for the info.
