SmartGuy,
If you are still looking, you might want to check out this AMP. It's a bit closer to Arlington vs Garland.
I continue to go there because they give great massages , although my regulars (Cindy and Linda) don't seem to work there and it seems to be under new management. The new girls aren't up to Cindy's level, but still have above average massage skills (esp. compared to the AMP's in the I35/Royal area).
I was only there for the massage+L1 so no idea if more is available. It's a different place from most AMP's, no shower for instance.
From the backpage ad for Swan Health Center:
4950 Belt Line Road, Suite 160
South West Corner of Quorum and Belt Line just off Dallas Tollway
Behind the Improv comedy club
Hope that helps.
