I had to laugh at this! DD now eats off the "adult" menu and knows that if she gets an adult meal, she cannot get a pop! I am too cheap as well!
However, DD LOVES

smoothies and will want to budget some of her own personal money towards these.
I also agree about the video games...we have tons at home and there is no need to pay extra on the ship to play them. I had thought maybe one night I would let them play but have decided that it is something that doesn't need to go into the budget!
I love to hear how others spend or budget for what they spend on the ship. I am very willing to spend money on some items (some photos, budget excursions, one or two drinks) but I am very conservative about other things (bringing our own wine/alcohol on board, no fancy coffee, etc).
Thanks for sharing!
