I have participated in conferences at both the Omni Mandalay (Las Colinas) and the new Marriott (which is right across the street from my current office). Both appear to be nice properties... I have no feedback on the rooms or upgrade availability, however.

I have also heard good feedback from colleagues on both the Wyndham Garden and Summerfield Suites (Wyndham program) for those with a Wyndham preference. Both are in Las Colinas.

All four of those properties are about 10 minutes from DFW airport (the airport is due west) and probably 10-15 minutes from the AA facilities for Saturday's activities.

Bob's for Friday night dinner is about 10 minutes due southeast of Las Colinas... easily accessible from that area.

If anyone is needing Las Colinas area directions that weekend, I would be glad to act as Las Colinas area hostess/expert since I live there.
