Ok, this may be long but. ..
I've stayed at the main lodge, very comfy, full electrical including A/C and hot tub. If you like to fish Lake Trout (I don't) it's perfect. If you like Walleye and the odd Snake (Pike) Dumoine is where you want to be.
The camps on Dumoine are very "rustic". Foam mattress beds, running water from a pumped up reservoir (disgusting). Outhouse, screened in porch. For me very comfortable. My favorite camps in order, Cedar Point, Moose Creek ( not always available) Park Line and Marion Bay (I won't go if that's all there is)
Cedar Point is right in the middle of all the hot spots.
Outpost camps have big coolers no fridge but they bring ice up whenever needed and they work fine, propane stove and bbq.
16' boats and I bring my own motor but he rents motors.
The reason I like the outpost's is you walk out and your fishing, the main camps you've got a slow 9km drive to the boat and half an hour to get to the hot spots. Inclement weather makes it worse.
All to say, I've been going for nearly 35 years, never came home without my limit and a few good feeds up there. Everyone I've brought, including my 7 year old son
(now 32) caught fish and most say it's the best walleye fishing ever. I wrote a story in Fish Hunt and Ride about it and I stand by it. It's my go too.
If you decide, let me know and I'll give up some hot spots.
