We run my airboat down there, generally in January due to deer season.
What guide? I may or may not know.
RE competition for hunting spots, we get out early, and have really never had much of an issue, if spot 1 is already taken we have fall backs.
Weather is a big factor on success, as has been big spreads... I can tell when we are too lazy to put out 12 dozen dekes, it seems to make a big difference.
Redheads and pintails is right. Can find other birds at times, cottontops are around, but you have to have good flight days and look over a lot of birds to take your limits consistently. And its required evening hunts at times to fill out for us. But fishing or resting is usually good during the day.
