Quick question. How convenient is the Hyatt Regency? Connections says it is connected to the convention center by an underground tunnel. Is that "walkable" or is it just for the DART? We have check in at the convention center before the sun comes up, so I want to make sure I am prepared for how long it will take and how to get there, I'm not a fan of walking in the dark with 3 small girls. There are a ton of hotels open now, so I figured if this one is not very convenient, I will switch really fast ;) I have three girls who compete on 4 teams, so we are back and forth from the CC to the Hotel ALL day all weekend lol.
