Several cabins, Usually two rooms with bunks in each + a small kitchen and bathroom for each cabin. Bunk beds, but comfortable, I think we had 5-6 guys in each cabin and then Tom has a wall tent too. Mike, I take my sleeping bag with me no matter what...but that's just me...I'm comfortable in it in just about any temp so I don't think about other bedding. I roll up my clothes for a pillow to cut down on bulk. Between the adrenalin dump of coming down after watching bears on the bait, a good hot meal and a late night campfire sit, I slept like a rock every night. You could have propped me in the corner and I would have been out. Take earplugs if you are a light sleeper, some of us going are world class snoring champs.
Definately take rain gear, I always have some wool too because I get cold easy. Temps range from low seventys to low 30's, bright sun to pouring rain. Most of the time, it was very comfortable though with low 40's to high 60's with a light breeze, partly cloudy.
Just whatever you do, make sure you have at least one working thermacell and extra pads/cartridges shipped up to Tom. I can hunt cold, and even wet, but it's hard to stay on the stand when you get light headed from blood loss
Number 2 priority is practice those close shots sitting. Those are the two best pieces of advice I can give you from my experience there.
Leafy wear may help, but, the bears know you are there. No matter what, them jokers smell you...at least most of the time they do. They have such a great nose I just don't see how they couldn't. The thing is, they just don't always associate the smell with danger cause it's all over the bait too. I think the camo helps to make them more at ease, but don't think you are really "hiding" from them, at least imho.
Holler at Tom, he may have a list of things he recommends to bring. I pack pretty much as I do any out of town fall hunt, just maybe a bit lighter to get all bows and clothes into two bags and a carry-on.
