We lived in Eau Claire from 1994 to 1997, so I can add a semi-informed voice to the discussion.
I would answer your question by saying, "no, it won't be like your lake cabin." The lodge itself is quite impressive, a replica of lodges in Yellowstone and the like. Magnificent tall lobby, stone, huge timbers. The rooms also are nice and large. The amenities are what you'd expect at a WDW deluxe resort, yet the WL is quite a bit less expensive than Boardwalk or Yacht Club.
We stayed there when our DD was 10 years old. She really liked the lodge and room, plus the proximity to the MK was a plus given her age. You may want to inquire about the consistency and quality of the boat service from the lodge to the MK. According to the boards, it can be spotty. We also took in the Whoop-dee-doo revue for dinner, which was a lot of fun and it's close by.
Good luck
