Hello DevCon-bound people,
There is a shuttle from the Gaylord Resort to the town of Grapevine and to the Grapevine Mills shopping mall. It costs $5 for a day pass. One interesting thing about it is that you can connect from the Green line (the one the resort is on) to the Yellow line, that connects to Dallas Fort Worth Airport. I was told that the day pass applies to both lines. So you could theoretically go in the opposite direction (airport to resort) for $5. The only downside is that you would have to transfer at the "Embassy Suites/Bass Pro Shops/Restaurants" or possibly at Wall Street (check the map).
Looking forward to seeing my colleagues...
