Yup, we were really worried too (there from April 26 - May 1) and it only rained on Friday night for about 30 minutes. Weather was beautiful the entire week - and we were all laughing on the Boobs Cruise Sunday the 29th because the weather report was so dismal for that day - the weather was perfect!! The only time I would believe the weather is in Oct. during the peak hurricane season, otherwise the "chance" of thunderstorms is like a tornado watch in the midwest - kind of every day in the spring and summer, but doesn't mean you'll see one ...
By the way, this is video I posted on you tube from Oct. 2011 when we were on our first visit and the weather sucked - tip of the day, Oct. is not the best month to plan a trip to Cancun: [ame=]Cancun tropical storm Oct. 2011 - YouTube
Same here. I was worried after watching the weather , but as the fireman said, not a drop fell that I saw. just go and have a good time!
