Crazyhorse campsite and site 6 ramp are only a few minutes apart. The Nautical is a "resort" hotel with its own low budget launch ramp. Windsor ramp is very nice, but they charge (I think its $10).
Camping at Havisu can be miserable during mid summer unless you have an RV. Temps can stay well above 100 all night and $60 for a A/C room is well worth the money. As far as boarding, early bird gets the worm. It gets blown out fast and is un-ridable the rest of the day.
Still a fun place. Hit up the channel, sandbar and coppercanyon during the weekend.
