We sailed for the first time ever on
DCL on 1/8. I allowed our kids (23, 22, 21, 21, 19, 16, and 14) charging rights. They had gotten Disney gift cards, Disney dollars, and cash to spend as Christmas gifts. On night 2 I began showing them how much they had spent via a print out from guest services. Thus reminding them that they had to pay me on night 4. On the afternoon of night 4, I went down and got a final print out from GS.
The kids gave me what they owed and I went back to pay it off. It worked out great for us. Some might find it a pain or too time consuming, for us it went well. Allowed my kids to see that THEY HAD to pay when you buy something with a "charge" card. They made great decisions about whether they wanted or needed something, lol! Also made the four 21 and over kids in our group more conscious about how much and if they were going to drink!!
