Would like to talk to anyone that has done this
From Lake Charles to Ponchatrain is a very lonely run for cruisers. No real Marina's, only industrial fuel docks. Fill up at Lake Charles, after that there is a Shell in Industrial City?, That caters to work boats. Once past Mississippi it is easy.
Monitor push boat channel. Super professional guys, they want to keep you out of their way, and will give any advise you want, even where to anchor or eat.
While not the most scenic area, it is very interesting.
I dread that portion cause the ICW is straight to the horizon, for days, and help is a long way off. At 7 knots you kind of go crazy.
We did it 2&3 years ago, about Harvey time. AIS would be a huge help, with radar. Once ran from Gulfport to Morgan City in Gulf then ICW to Beaumont, non stop. About three days.
In ICW it is longer, but you can go round the clock with correct crew. If you do run at night, go with a full moon so you can see. Only real issue is fog, barges will stop in fog.
We did it in 4 days. IIRC, the only trouble we got into was at Stingaree Marina, where we bumped bottom quite a bit trying to get out in the morning. Our draft was 5'.
Here are our logs from the 4 days of the trip.

When were you at Stingaree? I was there a month ago, completely shoaled couldn't leave intercoastal. <3ft.
Come down to Houma great marina or stay at the dock in my sons back yard free 200yards off the ICW MM62. A boat from Ontario Canada is here now, Jeff ( the owner) can from Ontario down the Mississippi River solo.
If you're leaving from Galveston you may want to go farther on the first day but if not... about a mile after you enter the intracoastal waterway going east there's community called Laguna Harbor Estates. They have great docking area, some with electricity. It's free! The developers keep it available to attract prospective buyers for their properties. They can be reached by phone but no reservation is necessary.
