Yes we also paid $5 a person for entry and were told entry was valid all day. The center was small but very well worth the money! We would have paid double but I can't imagine coming back later in the day, you can see everything in the first trip for sure.
The island is free to go to. Parking is hourly in pay slots. Unsure of cost for the center, its on the website.
If you have a hotel room on Tybee you don't have to pay for parking the nature center was five dollars for each of us and very interesting my grandchildren loved it
