Gigantic, cavernous, colossal, vast, enormous, immense, mammoth, massive, gargantuan, brobdingnagian, and titanic all describe the Austin Convention Center. I seriously believe you could comfortably fit a quarter million adult-sized people into this facility. Very clean, nice and cool, adequate bathroom facilities, huge ballrooms, good WiFi signal, the very definition of what a convention center should be. Needs more tables and chairs scattered around. Wear comfortable walking shoes, you will get 5000-10000 steps a day here going to a conference.
