Be aware - there may be hotels who don't know why people are booking that weekend/Monday in April so soon, why their hotel is full.

They will learn VERY quickly.

Last time, we had three club members who lost their "locked-in, guaranteed" reservations three to six months ahead of August, because the hotels realized that the rooms they booked at $50/night could be sold at $300+ a night instead. Luckily, we had LOTS of backups sites planned. They were able to meet at the family farm of one club member south of the path, then drive up early in the morning to a site along the centerline for a great view.

Just plan for something like that, just in case.
