A popular area of town that is easily accessible for travelling Ladies and also for the local gentlemen to travel to you, is the Arboretum area. This may not cover your boutique style that you are looking for, but the area is safe with well known Hotel names and close by shopping at The Domain, including several restaurants...

Also be advised that we take our security very seriously here in Austin, so you may be asked politely upon arrival to be frisked for concealed thingies and such...this is standard practice for visitors...
Hope this is a help to you; enjoy your stay; enjoy the gentlemen here in Austin, and have a wonderful day...
Thank you booking with the ECCIE travel dept...we are located on the main floor next to the gift shop....and I'm on the desk all week, folks....
