Yes best thing to do. Watch and wait. If they cancel you end up winning for waiting and the 48 hour to cancel policy is certainly a good thing. Today the 4/29 Mariner got cancelled as the Mariner is coming back to USA now on a new itinerary via Africa and South America so will not be in Europe. The booked guests on the 4/29 got cash back or a 125% FCC. Not bad for just sitting tight and waiting to see what develops.
