Universal does not do planned rehabs like Disney ( other than the annual rehabs of the water rides).If there are any rehabs to be done, they don't announce them till a few weeks before. So you will need to check back closer to your trip.There should be a sticky at the top of the boards. If you are going in Jan/Feb , it is likely one of the 3 major water rides will be down. They do them one at a time usually starting in Jan. The 3 majors are: Dudley Do right, Jurassic Park and Popeye and bluto bilge rat barges
