Tammie, the providers, rather than we gents can probably help you with the best tips. But I will suggest the following...
Avoid hotels in cities here in DFW with a reputation for stings. These include Arlington, Addison, and Irving.
A lot of the provider ads I see are for an area near the convergence of Coit Rd, the I-635 and I-75. There is a variety of lodging types there. The "long-term inn" (low-rise, open-air parking) type of place seems to be a favorite.
Another popular area with the providers is near the Galleria mall. The mall itself is located at intersection of I-635 and the North Dallas Tollway.
Thank you regreq. That is very helpful advice.
I posted in infoshare asking the same thing, to go along with co-ed.
If anyone has specific hotel suggestions, feel free to PM those so that they are not listed out in the open.
