Officials at the Shedd Aquarium, Adler Planetarium and the Field Museum say they will close for at least one day during this month's NATO summit, but logistical problems may lead two of the museums to shut down even longer.
All three museums on the museum campus will close on Sunday, May 20, the first day of the two-day summit.
However, nearby parking lots will be closed Saturday, and Lake Shore Drive will be partially shut down on Monday.
The travel inconvenience has left the Shedd Aquarium and Adler Planetarium wondering whether or not it will be worth it to stay open on those days.
Shedd spokesman Roger Germann told the Chicago Tribune that the museum wants to make sure it's easy for people to get there. If not, he says it takes away from the museum experience.
Both Alder and Shedd spokesmen said they need more clarification from the Secret Service on police parking and road closures before they reach a final decision on whether or not to say open. They said that decision is expected later this week.
