We will also be in the same cruise 🚢 coming from Toronto. I travel back and for to NY/ NJ all the time.
As far as the weather, there is no snow like what we have here right now. I would recommend the packable puffer jackets as they are easy to roll up back into the pouch it comes with. The weather is getting nicer but of course, you never know.
No boots needed. Less to deal with. Weather has been nice but check future forecast . Can always leave boots in car if you are driving in.
We are picking up my mom in Connecticut so we are not utilizing hotel this time.
Many Canadians on this cruise with the March break. We have left from Bayonne many times and have done similar itinerary with same ship but not on Canadian breaks so may see many on this ship!
