Very central location.
Especially if you are not planning on driving.
Depending on how long your Dallas stay is...
You can buy an extended DART pass.
Get to your hobby appointments on trains and buses..
I mean it does put a ding in your style....
but +1000 for discretion...
I'm not kidding, I have done this before.
Especially with the traffic being bad sometimes.
PM me, there's an app you can download for your smart phone that makes the DART schedule very friendly/flexible.
Well it's called ezDART-Dallas...
Still PM me tho for user tips if this is something you are interested in..
