No there are targets per cruise,
IE
Fare income.
Then non for income. Port adventures tend to bring in the most commission, in particular Europe and Alaska.
Adult dining.
Shops.
Bars.
Spa income.
Shutters income.
Mixology.
Boutiques.
There is a per cruise amount, do they can set itineraries which ones bring in the most income, and when, so low season and high season and holiday season.
The Bahamas 3/4 nights bring in the most pp, with two sets of cruisers each week. People tend to gave set spending budgets for photos and spa and shopping so pp the 3/4 nights bring in the most. IE if 50% of cruises buy a photo package that's double for the Dream.
Target wise non cruise fare income us quoted as a percentage of cruise fare income so they say they get a higher percent in Alaska and Europe with higher fares, then low season in the Caribbean where they get low non cruise income.
If you think of it each cruiser may pay differently for the same cruise, not just staterooms, but book first day, or book on board, or book later with raised prices, if book last minute, they plan all that, so it's per cruise not pp.
