March through November is the best time in my opinion. You'll avoid rainy season, have the best weather, and a large number of girls will be working everywhere. Around the holidays, they usually fly home to various places all over Mexico to spend lengthy time with their families.
The health check ups are very much a reality. I've seen the women's only health clinic that the women have to go to for their regular check ups and to get their health card. There is a steady stream of chicas going in and out of the doctor'no' office all day long. They get scheduled for follow up visits and if they miss them or fail the tests, they lose their health card. I also know chicas that showed up for work at HK and were sent home because their health card had expired. I believe the health cards are valid for 30 days.
