If I buy a Combo Ticket, do I have to visit SEA LIFE on the same day?

Yes, the timeslot you select to visit is your arrival time to LEGOLAND Discovery Center Michigan. You're welcome to visit SEA LIFE any time during the same day. This can be before or after your visit to the Discovery Center. The average family spends 60-90 minutes at SEA LIFE and 2-3 hours at LEGOLAND Discovery Center. Please see each attraction's website for complete hours of operation.
