I used it once in Boston because they had it set to only use with a reservation and it also was a large space so although they allowed several people in, there was nobody within 20 feet of me. I just used one machine, which I cleaned before and after. I would have left if crowded.
In Maine they have not opened gyms at hotels.
They have not reopened gyms in NYC where I live, and I’m not sure if I will go once they do - depends on measures taken.
