Yes, generally the parents can create any visitation schedule they choose so long as the needs of the children are not neglected. Visitation can be:
a) overnight (from just after school until the beginning of school the next morning) or
b) over the weekend (Friday night after work until Monday before school), or
c) it can be for several days in a row (one week on and one week off).
Visitation can also be for a specified short duration like a few hours for dinner every other Wednesday evening. Parents with rotating work schedules can negotiate flexible visitation schedules to allow for their time off. Some parents have occasional work travel requirements and so long as both parents cooperate, they can negotiate a visitation schedule which accommodates their travel.
