I was there about 8 years ago with my family. We did some thing where the company picks you up in a van at 3am and drives you to the summit to watch the sunrise (amazing sight, absolutely freezing with insane winds though). You then bike down the road and do a mini tour of the cane fields and surrounding areas (they bring bikes up in the back of the van). Groups are around 20-25 people if I remember right.

But definitely bring some windproof shells if you're going to the top.
