Last Saturday we visited Turtle Lake Resort (Union City, MI) in our RV for a night.
Friends from FL were on a tenting tour around Lake Michigan and we met them there. Website: Link Nice place, very roomy and lots of RV sites were available, as well as some motel rooms. It was very hot so we were glad to have the AC in our motorhome. The place is mostly up and running as allowed by MI COVID protocols. The main activities center and one bathhouse were closed (so stated on the website) but the pool area was fairly crowded on Saturday, not at all on Sunday. Not sure how well the stated pool occupancy guidance of 16 bathers was followed later on but we enjoyed the pool very much in the AM when it was less crowded. The lounge chairs and tables were well spaced. They had a band playing at the pool Saturday night and the area did get crowded inside the pool fence. Staff members were wearing masks in the pool snack bar and at the office where only 4 people were allowed at a time. I did not see anyone else wearing them except ourselves in the bathrooms.

Anyway it was a nice nekkid getaway from all that is happening out in the real world!
