A great location for families, you can keep younger kids busy for hours. The hands-on exhibits are 'life size' and very detailed. Planes, cars, store fronts, all very educational as well. Kids are corralled in areas that make it easier for parents to stand back and watch or there is plenty of room for them to get in too.
If you are looking for an event space in Raleigh it is certainly well worth a look. The wide gallery spaces, downtown location and helpful staff make having an event there very easy.
