It really depends how you operate and your clientele. Most of the hotels in the Galleria are big enough that if you have guys wandering in and out in business or biz casual clothes, no one will notice. Let me tell you, I live in that area and there are so many drunk civilian hookups going on, if you aren't wearing an ECCIE tank top, I can't imagine how anyone would notice that you're working.
If you're seeing 10 guys a day, it's going to be an issue no matter what unless you stay at a notel, I suppose.
My opinion has always been, the bigger the better, the more anonymous. Plus if you have a cover story, it's even better.
Honestly, the only time I've been treated like a hooker was when I wasn't being a hooker...just being a single girl.
