Argentina should still be good, have been there countless times. Hundreds of escorts and sensual massage chicas, indie or in privados. Argentina peso great value now. However, a lot of the fun was at the night clubs in the 2000-2012 golden era. They have now been closed for many years.
For Toronto and Montreal reviews see Terb and Merb.
I concur on Panama too, the selection is not as vast as other cities but enough to keep you busy, plus they have a couple decent nightclubs. Habanos is now called Don Julio's, currently the selection is down from pre-covid but still dozens of chicas there from Colombia and Venezuela, and a few from Cuba too.
