Directions from Hilton Garden Hotel: When you exit through the hotel entrance, turn right. Start walking (though the parking lot, or on the sidewalk to the left of it). Keep walking until you see a building (this is the Union East). Turn right again to enter that building (there are sliding doors). Inside the building, head straight - when you see a staircase, climb three floors up (until there's nowhere else to climb), or take the elevator. From the staircase, the Tomas Rivera Conference Center will be on your left-hand side. (There will be signage, but just so you get an idea.)
