We also are on a budget. I found that buying one soda card would cover myself and my husband. It was my husband's card so He would bring a container( given with the card) and fill it up with ice and soda before we debarked. Also he used the same container for juices and lemonade which are free allways. Pictures can be expensive $25 and $16 each. We also purchased liquor on board the 1stday which they let us take to the room. I wiuld use the soda and make myself a drink in the room. You can do it! Especially if you do not drink. Drinks range from $3.50 a beer to 6.95 a mixed drink. Have fun! We went on our 1st cruise on the Navigator this past April and in Feb. we will be cruising on the Grandeur with our three kids, 22, 17 and 14. We are hooked and RCC are fantastic!
