Couple more questions that I thought of based on all of your excellent responses:

1. Which Admiral's Club is best? A shower is tempting. Can you help pinpoint it so I know how to get from my gate to the AC?

2. If my meeting is at Love Field at 11am or 11:30am, how long should I leave to get there?

3. Based on my above two meetings and their times (one at Love Field, the other in Irving), is it better to rent a car or take taxis?

Thanks!
