5 days notice is simply rude in such an industry, where they easily have the capability to notify farther ahead when they already know it will be closed.
The problem is they haven't said that publically. So they are leaving those of us with other arrangements - other hotels, air, pet care - to wait it out.
I take no chances about canceling on my initiative as compared to being notified. There are a lot of reasons that things can work differently. If for some unbeliever reason the second part of my stay were to become valid (late May) I'd be left with different conditions. Call me gun shy, but in the cruise industry it makes a huge difference if you cancel vs get canceled right now. Not gonna chance it.
