Okay, I'm the oddball but I voted they weren't fun. Unfortunately, the time we went in June '02, Space Mtn broke down twice, the crowds were huge, the waits were at least 30 minutes and since the park closed at 10, I thought 10pm til 1am was just too late. We also did not have Early Entry then and if I had a choice I'd take EE over e-nights anyday. It may be different in off-season with the times a bit earlier.
