Hi Nicole,
I am green with envy - it sounds like you have booked one of the most amazing voyages! You'll find that just about everything is included with your cruise fare. There are a few activities such as bingo and the wine/beer/martini/cognac tastings that require an additional fee. The tastings range from $12-15 per person and the bingo varies depending on the game and equipment package you purchase between $30-90.
Things I would consider budgeting for would be:
Room Service - The food is included, but it's customary to give a gratuity to the person that delivers it to your stateroom. I like to tip based on how much they bring, typically $1/item with a minimum tip of $3
Spa Services - I spent a significant amount of time in the Spa on my last cruise, and this is something well worth budgeting for! You can find pricing
HERE.
Movie/Show Snacks - The theaters sell a wide variety of snacks and beverages. They are pre-packaged like you would buy at a movie theater and priced about like you would expect at a movie theater.
Alcoholic Beverages - These are not included in your cruise fare, along with any drinks purchased at a bar or from a server on deck (such as bottled water, or soda). There is a self-service drink station on Deck 9 aft that has a selection of complimentary fountain drinks, coffee, tea and hot chocolate.
Gourmet Coffees - Also not included, but worth every penny! There is a coffee-house style establishment on board called
Cove Cafe where you can purchase lattes, cappuccinos, espressos etc.
If it were me, I would probably set a budget of about $30/day per person for incidentals....but I like to buy a lot of coffee & bottled water!
