Power outages are not a big deal. They come and go, sometimes more frequently, sometimes less so. If you are really worried about it, just make sure you book a resort with a generator. They can be a nuisance for those of us who live here but for a visitor, they are just part of the adventure and charm. Many very good resorts on the mainland and in Mexico on the Yucatan don't even have power at night and that makes them even more appealing. I remember coming here as a tourist and how lovely it was to come back to our cabana in the rainforest, lit by kerosene lanterns. Most of the local restaurants depend on gas for cooking, so you won't go hungry. Not much you can't do with a big of gas, candlelight and the Caribbean Sea. In fact, I can think of a lot of very fun things you can do.
