We gave her a whopping $5 after she had done 2 things for us already. She was VERY appreciative and she was a blessing to us the entire trip....we gave her the normal recommended tip at the end as well as $10.
$15 extra dollars is not a lot to us...but it is a lot to these fine folks who go 7 months without seeing their families. We have never tipped prior at the beginning nor at the end...until we read comments on this website from people who did and recommended it and let me tell you....we've always had great stewards except for one cruise....and I'll do it againin Oct! I think it's worth every penny. Especially the look on their face that you appreciate all they do for you.
