Haven't been to that resort but I do enjoy the fishing on Nipissing As mentioned, lots of pike, nice walleye (pay attention to the slot) and some very nice musky in those waters. Definitely take your time and watch out for the rocks, they are every where.
Lures. The best lures are ones that you are familiar with and comfortable using. That being said, for those waters, I like gold/brass, orange/reds, clown pattern, suicks, jakes and husky jerks for the essox species Walleye, I often use leeches or every day worms.
Have a great trip and post pics when you get back!
