Agreed! Plus even if it IS open and the ship cannot dock for any other reason, you still wouldn’t be getting there. We were “stuck” onboard the first day of a Double Dip in July because a tropical wave parked over the island. All indications when we docked were that it would be a temporary shower - within a couple of hours it was clear that it was NOT, and the island was evacuated (after those braving the rain had to shelter in the bathrooms during severe thunder and lightning - but we stayed at dock because it was safer there than trying to get out of the channel in that. We got no compensation (well, there was no ship-wife compensation - I suppose some squeaky wheels might have raised heck...I was too busy enjoying the ship) - but the cruise staff team worked their butts off adding in activities. Was it disappointing? A little, especially since the Double Dips are usually more expensive. But I got over it and made the best of it.
Besides - Castaway is the one port where it is not like you could have outside excursions booked to worry about giving notice to.
You are going on a
Disney cruise on the beautiful Dream or Fantasy (at this point). Enjoy the whole experience, whatever it brings.
