One thing about Ely is that there are soooo many lakes to choose from, that the best (in my opinion) is overlooked. The first lake you come to IN Ely is Shagawa. I go up there at least once a year. The walleye and smallmouth fishing is absolutely incredible. There are also many northerns over 20 lbs. There are 3 resorts on the lake that I know of. Stoney Ridge, Shagawa Inn, and Olsens Bay. Olsens being the more spendy of the 3. Hope this helps.
P.S. I will probably be up there around the first of September, so if you decide to go there mebbe I could show u around
