We tried Hanlan's Point last summer on a Saturday visit and had a great time. While you are correct about the demographics, (I'd say 50-50) it was worth it. It's not much different than South Beach or Haulover. Biking or rollerblading in the park with an afternoon cool down on the point is a great day. We just set up near the water.... and looked at the water. It would have been great to have you two next to us to push the mix our way!
