Sorry, navybankerteacher, but you're wrong. My diet consultant advised on weighing every day, and so far I've lost 70 pounds. There's nothing wrong with wanting to be aware of your weight while on a cruise.
This is the first time I've ever posted on a forum like this, and I really appreciate all of the feedback. I think in the end I'll just take my own small scale, calibrate it before I go, and only use it in port! Thank you all!
