Last week of June 2022.
The property itself is tucked in a great location with private access to nice calm and quiet lake. Complementary paddle boat and kayaks were perfect for this location. Although a motorboat is available for an extra fee, you really wont need it. Evenings and nights were quiet and peaceful.
The home/cabin is BIG and very well domesticated. You almost wont need to bring anything. On your way in, make a stop at Snow's Market for basic provisions and you're good to go for as long as you stay.
Access to ATV/UTV trails is right off the main road near the cabin. We made trips to town for supplies or lunch on our ATVs. Expect some ATV-route hops to transition between trails. Also, the local maps aren't very detailed and are not up to date. We ran into so closed routes/trails sections and had to GPS our way around a bit. We also didn't get to truly explore that VAST network of trails because there just wasn't enough time, but as I mentioned, it is VAST.
If you don't feel like cooking, there is a local eatery down the street, which was pretty good for the area: Cranberry Inn.
As for the town of Mercer itself: keep your expectations on the lower-side, and be ready to adjust as you go. The people there are pleasant and very welcoming. However, you can tell everyone operates on some kind of season-driven schedule. The problem is, you can't tell when anyone is "in season." The trails are for ATV/UTVs, but they are also for Snowmobiles. So you really don't know when any of these places are hoppin' and at what time of the year. Many local businesses (restaurants/eateries mainly) tend to not stick to open/close schedules.
