I’d be quite upset with that revised itinerary, only 2 ports. I’d rather skip PC instead of Nassau, although I’ve been to Nassau many times. Arriving so early in PC could be a positive if there is an early excursion to Disney. It’s about 75 minutes to Magic Kingdom. If the excursion can get you there at 9am, you’d have a good 5.5hrs to explore. If Disney is of no interest, there’s Sea World or Universal. And, of course, the spaceships. Just trying to make lemonade out of this lemon.
