That is a very hard question to answer. Do you gamble ?/ Do you drink alcohol a lot or moderate.? Do you shop for lots of souveniors? There are so many factors to consider here. Be more explicate.. Sorry to be no help.. Char
You didn't mention which ship you are going on. If tips are automatically deducted from your sail-and-sign account at the end of the cruise, you won't need to bring cash for tips (though you might want to set a little aside because you will no doubt want to tip above the recommended amounts for outstanding service).
It's possible you will have to bring cash for tips. If so, set this aside in an envelope in the safe and don't touch it until tip night.

Yes, I would think $1000.00 would be plenty, don't forget you can use your CC in the ports too, you'll need cash for tips, gambling and purchases off the ship, all your shipboard charges will go on your sign/sail card and in turn get charged to the credit card you give them upon embarkment, so you won't need cash for that...... Be careful though, those charges do add up quickly, but on Navigator you can check your balance through your TV in your cabin...have fun!
Mak: My wife and I cruised the Triumph (Western Caribbean) in April. I took $1,300 US Cash (we are from Canada) and did not bring much of it home. Although we secured our Sign and Sail cards with a credit card, we paid if off with cash to avoid the "after effects" of credit. Our S &S bill was about $650.00 (our tips were prepaid), of that, about 400.00 was bar tab (wine with dinner, etc), 250 was one excursion for 2 (river tubing in Jamaica-great fun) and some items from the duty free store. The balance was shopping in various ports, probably blew $350.00 dollars in the casino--rest was extra tips in ports, some duty free liquour in Cozumel, drinks at "Fat Tuesdays" that sort of thing. So, I would say $1000 plus access to a credit card would be plenty.
We had a great time and don't regret spending any of the money (well, the Casino didn't seem to pay off bigtime for anybody, so you could avoid it and save some money--but the flashing lights and chiming machines are pretty attractive).
To be honest, we take anywhere from $1500 to 2000. We do not use credit cards and this money also applies towards our getting there/returning expenses. We usually come back with a few dollars. As I stated earlier take as much as you can spare, better to be safe. One cruise I severely sprained my ankle and suffered from dehydration. My infirmary bill was almost $800 and we did not have a credit card so there went our cruise. No more tours, pictures whatever. So make sure you are prepared. BTW my medical insurance company did cover the bill but it took 2 months to get paid. Happy sailing!
You might want to check whether your ship has an ATM on board. I found one in the casino on my last cruise and switched from credit card to currency for many expenses but didn't have to worry about having enough cash for tips at the end.
