What a great trip and a great cruise! Here are some thoughts that may help everyone. This was our eighth cruise but I will try to write this for both first time and experienced cruisers.
GOOD
What an awesome, beautiful ship. Very easy to learn your way around and the signage is excellent. (you do need to know that forward is the front of the ship, aft is to the back, starboard is right and port is left). This ship might honestly be too big for some, but it wasn't to us. We rarely felt crowded (exceptions were around the pool on the st sea day and in the immigration line).
