We went on our 12/4-12/11 cruise and were some of their first customers! I spotted the sign coming over the brigde to Atlantis and a group of us went before heading back to the boat. They had some kinks to work out. The bathrooms were not completed. Still had contractors working. Everything was new to everyone. We had 8 people in our group and had about 8 waiters and waitresses. I can't remember how many times we ordered drinks. Everything came out hot and delicious, though!
Funny thing, since it was their first day open, cab drivers had NO clue where it was! Conceirge at Atlantis had to come and give directions to the driver.
