DH & I went on a 2 night "wannabe" cruise 9 years ago. We are getting ready to sail on the Wonder 3/21. We have 2 sons, 6 & 8. I am beginning to panic over what to pack! Can anyone help me? I know we need swimsuits, but I am lost over what we should wear to dinner. Kids included. How formal do we all need to be? And, does anyone know how warm it should be in March? And, can we bring sand buckets, etc.? THANKS!
