The third floor of the exploration center, *not* the research center (with the giant globe). The entrance is located across the street from the NC History Museum.
There is free parking at 101 N Wilmington St, Raleigh, NC 27601. It's about a block away from the museum. This is the cheapest place to park while still being close to the venue.
We would much rather focus on the party aspects of the wedding.
The rest of the floors will be blocked off, but there is plenty to see on the third floor.
The sloth has a strict bedtime of 9:00pm. Sorry.
