I’m planning my first cruise for September. What tips and suggestions can you tell me that I won’t find in a brochure?

I’m a AAA member so would I save going through their travel agency, or booking things separately myself, or booking the airfare at one place and the cruise at another? I will need airfare from Pittsburgh PA to Miami FL, as well as transportation from the airport to the port. At this time I’m looking at leaving the morning of the cruise not the night before that way I won’t have to worry about hotel expenses.The cruise line is Royal Caribbean. Any advice for me??

Im turning 16 next year and im planning on going on a cruise, but i was wondering which cruise is best for teens (such as the carnival, royal caribbean etc). And also what events they have. Thanks[:
And we’re planning to go to the caribbeans

I am planning a cruise to the caribbean. I see a bunch of different options. Basically, I want to know what are the BEST and which ones are the WORST?
And why?
Thanks!

Why do "discount" cruise company advertise up to 75% off of brochure prices, when their prices are actually exactly the same as the brochure prices?

Would it be possible to catch an 8:30am flight when a cruise ship arrives at 6:00am? I don’t want to end up missing my flight out of San Juan.

I am planning a cruise to Puerto Rico, St Maarten, and St Thomas, will I need a passport?

My class would like to go on a cruise, but we need an educational reason to go.
Do you know of any activites where we are learning while on the boat that would be a better experience than in the classroom?
We are from Seattle.
