Well first thing is tips. $10 per day per person, so for two people on a seven day that is $140. Drinks are about $5.50 (for the fancy stuff) and bingo is like $20. If you gamble then include money for that. Also I would get one fountain card to share, which should be about $6.5 per day. If the ship has a special restuarant that will cost about $30. I would do the restuarant once during the cruise the steaks were amazing on Freedom. So per day for tips, 2 drinks, bingo, restuarant, and soda. About $77.5 per day this does not including Shore Excursions or gambling. All the numbers are my best guesses and maybe a little higher or lower. I would per order and pay the Shore Excursion and bring $100 per day per person or $1400 for a seven day. You may not use all this money, but better safe than sorry.
