I posted this on GIS too, then realized that I want answers NOW

I have never been to a gym before, and am planning to visit two tomorrow for information on memberships, (for some reason they don't like to post membership rates online).
I am going to choose between 2 ladies only gyms. Mademoiselle Fitness, and a smaller non-chain ladies gym in in town.
What should I ask/look for when comparing the two?
Should I just stick with a traditional unisex gym?
