My wife and I just spent 4 nights at the Lakeside Cabins Resort. It is a gated community that is open during the day, and gated off at night. It is located about 1.5 hours from Chicago, though my wife and I kept remarking that we felt like we were in the Adirondacks or Seattle. The setting was perfect. We loved the grounds, the lake was great, and the cabin had a back deck that was right on the lake. The fishing was great! I caught a lot of sunfish/blue gill/crappie, but I saw a lot bigger fish in the lake - possibly muskie/walleye? The lake was beautiful, but the LED light/sprinkler was very tacky. We felt that the lake would be much more scenic and beautiful without the LED light/fountain in the center.
My wife and I pretty much had the resort to ourselves, as we were there in mid-September, during the week. It was great. We enjoyed the community bonfire pit behind the community center for a couple of nights. It would have been a bonus if we were able to have a fire at our cabin, but this was just fine. We also used the community center to play ping pong, foosball, Pac-Man, and some pinball games.
The grounds were amazingly clean and well-kept. But the cabin we stayed in was a bit of a problem. The carpeting was stained and dirty, the pillows were stained and gross (the management did bring us a couple of new pillows, but we ended up using the ones we brought with us), the blinds were broken/bent, the outside cushions on the chairs/benches were covered in mold and unusable, several lights were broken and/or missing a bulb altogether, and the main TV/stereo did not work. I guess it was a good thing that we didn't have cable, but I wanted to watch the football game (the one time I watched TV the entire trip), and I had to do it with my own mobile data - set up a hotspot onto my computer. Not a huge deal, but the management sent out the cable guy, which we had to deal with - and was one of the things we came to the woods/cabin to escape. The management was nice about the situation and ended up refunding a night's stay. So that was much appreciated.
We enjoyed going to Union Pier/New Buffalo - only about 5-10 min away, and visited several wineries/breweries/distilleries (Round Barn and St. Julian) while in town. We really recommend you visit Jenn and St. Julian - she was great! We will definitely be back, hopefully sooner than later.
