My family and I are taking a cruise for the first time (husband, myself, and 8- and 5-year-old children). We've prepaid for us to have unlimited open bar and two specialty meal packages - may do more, depending on what husband wants to do. We are pre-paying for tips, so not worried about that. We plan to book a few excursions, too.
Since all expenditures are added to the NCL Onboard Account, what's a good amount to budget for?
