I just got off the Quantum a few days ago. Here are a few observations and my own personal perspective.
The ship is beautiful and the staff was awesome. Each and every crew member I interacted with was friendly and helpful.
Getting on board was easy and well managed. Getting off at the end of the cruise was also quick and easy. Be advised that if you intend to use Uber after the cruise to get to the airport, the ride-share pick up area is a bit of a walk. Especially when you're dragging a bunch of luggage.
