Online check in, pin without credit card

[Hezzy04]

I just completed online check-in for my family. I did NOT enter any credit card info (don't plan to use MB to charge anything) but I DID set up PIN numbers for everyone in my family.

By doing it this way, I assume we should be ok to access our dining plan, right? We just need the pin for that?

Also, I set up a PIN for my 3 year old and 4 year old...so with that, they should be able to also use their MB to access the dining plan/meal credits when my husband and I aren't around, right? One night my parents plan to hang out with the girls, so I will give them te PIN so they can feed the girls.

Thanks in advance if you can confirm any of this or give me more info...
