I went down to cancun on a stag from mar 10 to 17, and we went out on a boat called "stuff it" through cancunfishingcharters.com. The guides were good and very knowledgeable, not the greatest english but got us into four sailfish and we landed three. One was 84" one 78" and one 74".We only ended up fishing for about 2 hours after about a hour and a half run from the dock as four of the six guys i was with were puking there brains out! As for the company, they were ok and would go back on a charter again.. Just make sure you only buy what booze you want off them as they took two cases of corona back as we did not drink it cause of the pukers and the two of us that weren't sick were drinking a bottle of jack daniels that i snuck on.. They did not refund the guys for the beer and needless to say they were a bit mad cause it was way overpriced when they bought it in the first place..lol
Do not know of what it is like when you are going down but thought you might like some feedback about a company..
