The work is being done by Chinese nationals. Two shifts/day. We were at 3 Amigos in Jan @ 5 pm and about 75-80 of them walked out together and went up the hill past the casino. I have no idea where they could be staying. I asked Sam(works for the lagoon authority and manages the bridge openings) how many Chinese contruction workers were on the island and he guessed about 1000. I found this amazing.
