Ask the front desk if they have a shuttle. Sometimes airports will drop you somewhere if the shuttle isn't busy.
their answer was to take their airport shuttle to dfw, take the south parking lot shuttle to the south remote lot, from there walk to a TRE station, take the TRE a few stops and then take a cab (now only $20, but 1 hr 45 min total, and not really up for an adventure).
was not much improvement there. thanks for the idea sd. its not a terrible problem, but i get kicked out of my room soon and then i'll have to wait in the lobby for too long for them to swing over, so if anyone was already over here (rental car or staying near here etc) then it'd be nice to get a ride over
