best way to book 2 rooms?

[saraheliz]

i am planning on going to disney, staying a por at the end of april/beginning of may. i am going with my mom, sister, and daughter (2yo). what is the best way to book two rooms? my mom is paying for the trip...so should i-
-call and book two rooms under her credit card?
or
-call/use online and book one room under her name/credit card, and one under me or my sister on one of our cards?

we will be travelling in two seperate groups (me with my sis and dd, and my mom from somewhere else). i want to make sure that there aren't any issues with us checking in if we arrive several hours before my mom does. also, want to make sure that there aren't any issues catching dme with two seperate flights/times under one reservation.

thoughts?
