What would be the best time of day to visit the aquarium

Weekday mornings. Not to crowded

We went about 4pm on a Tuesday and parked at the top of the garage. Not crowded at all.

Like everyone said, early weekday morning. Tues, Wed or Thurs morning. If you're a Veteran, you park free in their garage.

Also make sure to buy tickets online and go through the gift shop at the beginning and see it backwards. You'll skip 95% of the lines that way

As soon as they open on a weekday, get there when it opens.

I went on a Thursday morning about 10am, an was no crowd an didn't have to be in a rush

We went around 11am on a weekday and it was not bad. Just the parking garage fills up fast so had to park at a different one and walk a little. Wasn't bad though

Evenings

When thay open till 1 trough the week it's not crowded

I agree.
