As far as electric, water, etc, for tourist accommodations, no issues. There are some scattered residential areas that apparently still do not have electric, but otherwise, things should be fine. Wifi, I'm not sure about. As far as restaurants in Simpson Bay, pretty much everything is open. Restaurants in Oyster Pond, I'm not at all sure about. Infinity Restaurant at Oyster Bay Beach Resort is open, but otherwise, not sure. Suggest you check that pinned thread that Georgia referred to. As far as safety issues, even more than before, avoid some purely local areas after night., and follow safety precautions, don't flash money or jewelry, if you use an ATM, be careful, watch your surroundings, and preferably do it during the day only. Grocery stores are open, except for Carrefour in Cole Bay. Rental cars should be fine, as even though a lot were damaged, but the demand isn't nearly what it was.
