experiencing a rotating schedule in an uncooperative, non co-parenting friendly parent relationship.... i can say to you that i would at the very least rethink the schedule that you have in mind.
our children, 3 and 5 at the time of implementation, have adapted tremendously. however, now i can see where the schedule could be less of a burden on them. if i could convince the other parent that reducing the number of exchanges would be more beneficial to the children, our schedule would be less complicated for our children.
if you live within 5 miles of the other parent and have a cooperative co-parenting relationship, a 3/3 rotation can absolutely work and be healthy for the children.
otherwise, the shifting/transfer from household to household becomes burdensome as they get older. different households, different rules; letting their friends know what number to call them at or if they will have a computer available to them, etc... most of the time, because of the alternating weekend (or saturday like you are suggesting) my husband and I cannot keep up with the schedule without keeping a calendar. it is confusing for the parents. even when I have tried to provide them with calendars.
the adjustment period when arriving at either parent's household can be 1-2 days of irritability.
I am absolutely an advocate of 50/50 rotating schedules. it is the best thing for the children when implemented in the right manner. and what works for one family may not work for another. but what to look at first is what schedule is best for the children... not the parents.
my suggestion would be to consider a full one or two week rotation (two week is preferable)
just my experience... hope it helps.
our children are now 10 and 12
