UPDATE: Dallas is now attempting to launch itself into the 19th century with rail transit (otherwise known as TRAINS). I have zero experience of the service myself, and can offer no opinion or recommendations. Check the website, and see if it looks like your sort of thing. It is an option, at least. Keeping in mind, they don't operate on Sundays. Because, apparently, people don't travel on Sundays.
For those of you flying in for the weekend and not planning to rent a car, a cab will run about $40 between DFW & the Adolphus, and about $20 between Love Field & the Adolphus. There are also the SuperShuttles - at about $40 for two people.
This may not help you get FROM the airport to the hotel, but the Adolphus does offer hotel shuttles TO both DFW & Love Field airports. The cost is $17.00 per person one way, and they depart at 5 minutes to the hour and 25 after the hour. No reservations needed - just show up! Certainly a better deal than a cab!
For those of you brave enough to rent a car and take on Dallas traffic:
