the Moon Palace will be a gogeous huge city when finally finished, WHEN finally finished. it doesn't look like such may happen very soon.
IF they open anything during january or february 2009 it will be a small piece within a huge construction site.
The Elegance will open november 14th, i've been there for a private tour yesterday, looks just amazing. not all amenities will be ready on opening day nov 14th 2008, but it will be completely running for christmas 2008, so no prob for your upcoming visit.
happy travel
Mike
