We are a family of four on FD for our first time on the dining plan. My question is how the credits are allocated and used up. If I go to pick up a snack for all four of us do I need to to take all 4 keys with me and have 4 transactions? I am trying to understand if all credits are available on each key or does each key only have 1/4th of the total credits. Do I need to track how many credits are used on each key? One more question...my DD and DW would like to do more TS meals while my DS wants to do CS to have more time for rides and not sit around for TS. Can my DD use more than 1/4 of the TS credits as long as we don't exceed the total TS credits? Thanks.
