I have always wondered how many other women traveled alone on home exchanges, or on any type of trip. What the ratio is of the solo female traveler, versus couples, versus solo male traveler because I always feel like an outlier, especially when the home exchange that greets me is all set up for two people: two sets of towels, a bottle of wine or champaign with two glasses, little rose petals on the master bed, and pastries or other little treats, always enough for more than just me. And then I wondered what the odds would be of my entering as one and leaving as two. Maybe one time? Just for fun?
