Hi Mark...I think they do. In my experience, the ones who are staying at smaller hotels do so because it's not their first trip there and they have a Dominican boyfriend. Groups of single female tourists are more likely to stay at an economical all inclusive like the Boca Chica Resort or the Don Juan. This has a lot to do with single women being concerned about safety issues while travelling to a foreign country and travelling on a buget. When I travel to Santo Domingo I notice on the flights from Toronto it's mostly couples or families. Puerto Plata usually comes up a little cheaper in the last minute deals from here, so you'd probably see more single Canadian women there. As I said before though, there are a lot of German women who travel to Boca Chica...In the early fall (September) there are also quite a few South Americans.
