My son was drawn last year. It was a Great Trip! We stayed at American Inn and Suites in Port O'Connor, about 15-20 minutes from the main gate to the WMA. Nothing fancy, but clean. The section we hunted had another gate closer to POC, so that was a bonus.
It was pretty hot, and the mosquitoes are something else! Getting around on the roads is easy enough. Off the roads it is rough, marshy brush. It looks completely flat, but maybe knee-high grass, or chest deep water.
We only saw one a few whitetail in the early morning and evening time. We saw a nice 10 pt whitetail, at about 10:30 AM but couldn't get a shot. About 11:00 the same morning we saw a Sambar bull, in velvet, out in the marsh. Fortunately he was busy feeding, splashing and making a bunch of noise, so we were able get in to position for a shot. My son hit him in the heart and lung, (.270 150gr Sierra Game King). The deer ran ~50 yards and piled up on a small island. We got him gutted, but were not able to move him, so had to call the guys at the office to bring the ATV out to get pick him up, which they did, no problem.

Here he is feeding in water up to his chest
Field dressed, he weighed 308 pounds. The meat is Excellent!
Taxidermist called this morning, shoulder mount is ready

As for advice, I would look for the sambar in the water during the middle of the day.
They are covered in ticks - bring Off and extra trashbags or whatever to wrap up the hide/horns.
Bring "The Big Cooler(s)"
Best of Luck!
