Leaving the boat in the water for 8 days should not be an issue. I do that long once a year and several other times for 4-5 days.
Put the boat in at PB2 and leave the trailer there for $5/day. That is what I do.

What Griff said with trailer.

Then plan on a replacement Liver after 8 days of Pain n da Azz's !!

Whoop!!

Point Randall is also a great place for fuel. Quiet place to dock and always low prices. 93 octane non ethanol is 3 bucks. Didn't look at the price for 87 but my guess is it is around 2.50, also non ethanol. Most everyone at the lake for a week leave their boats docked all week. Once in when you get here and once out when you leave.

I agree with what others have said. My favorite part of going to LOTO is that after I launch my boat, I literally park the truck and do not touch it until it's time to load back up and go home.
You can get virtually anything you need, via boat, on the water.....including a massive hangover and a BUI. Be careful and have fun.

Around the point from Coconuts, half a mile in Indian creek branch is the family party cove. A nice raft up location. I think its dry branch cove on map, before copper roofed house.
