For us, the reason we ended up with so many snacks and extra quick service credits was because our little kids just couldn't eat all that food. Also, we often ended up sharing (especially the aforementioned children) so that saved up our credits, even when we didn't mean to. Another thing that happened was that our youngest came down with a bad cold near the end of the trip and so dh stayed behind with her and one of our other kids while the two teens and I went to a park. That severely cut back on what credits were used that day. We had over 20 snack credits (either from snacks or from breaking quick service credits down to 3 snacks just to get them used up) to use! We also ended up leaving 3 table service credits unused. I think it's harder the longer your trip is, also, combined with the more people you have. With 6 people and 8 nights, we'll have 48 snack credits to use up over the course of our trip!
