Floating is still on for the 24th. I just called NRO again, we won't need reservations this late in the season. Prepaying will not be necessary. They offer two free nights of camping when you pay for a float trip. 6 person rafts are $120.
Camping Friday, floating Saturday, and camping again Saturday night sounds good to me.

Don't trust your iPhone to work, write that shit down on your arm or something.
Beer with gold top cans is the only type allowed on the river, so keep that in mind.
