Hey Kieth
Sounds like a great trip, don't know when you are planning on going but the marina has been full early Friday for the last few weeks. Try to get in early. As far as entrance buoys, I am still using my plots from 3 seasons ago w/o a problem. There is a small tree that sticks out about 8 feet or so above the water when you are about a quarter to half mile from the lead entrance buoy. Follow that path straight to the outer buoy. Done deal.
Have Fun
