- It does depend on the day, but generally SEA LIFE Charlotte-Concord Aquarium is quietest after 3pm. Like any popular attraction we have to limit the number of guests at any one time. The best way of ensuring your child’s place is by booking your tickets in advance HERE. (it will cost less too)! Please be advised that all ticket sales are non-refundable. The average visit takes approximately 1-2 hours, but once inside you can stay as long as you like!
