The counsellors are not a "tipped" position. There are various threads on accepting cash. If you want to do it, put it in an envelope with one person's name on it. The phone cards were popular, but as many have cell phones, this isn't such a good thing any more.
Some people do gift cards to Target and
Walmart--where the crew bus will take them on their port time. They have vey little off time. Unless you put something in an envelope addressed to a specific individual, the cards, etc. are used as prizes at the crew parties that are thrown with the money tips given to the counsellors in general.
Some other ideas....they love candy and treats. They normally can't eat the same food we do, so if you happen to get an extra dessert and it happens to get delivered to a late night cast member in the club or lab.....
I used to ask DD if there were one or 2 counsellors who made her time special--send them a thank you note with whatever you decide to do. Also, be sure to name them on your evaluation and/or write a note to
DCL afterwards. A note in an employment file goes a long way......
