Definitely agree on BOG for good use of a CS credit for breakfast. Paying out of pocket, it's not really worth $25 to me, but one CS credit it is for sure!
Better yet to get a pre park opening reservation! Go, enjoy breakfast, then ride a few things before lines get long. We rode 7DMT twice with empty cars after breakfast, then they offered to let us ride again (but I thought that was enough)!
Most QS breakfast are otherwise quite inexpensive, so not the best value on the dining plan. You can get lots of things for a snack credit, like biscuits & gravy, which are filling enough to me!
