The new club at Moon Palace is great (Noir is the new name, no longer Andromeda) - good music, great set up and a huge screen for video projections. No doubt you'll have fun there. Bar crawling may be a little bit difficult as they bars/restaurants are not too close together and you may end up waiting for quite some time for shuttles between the different sections. The Sunrise lobby bar is right outside of the club and they also have live music later in the evening. The Sky View Lounge is also close to the club and it's a good spot to hang out at. Bar/Club employees were great and went above and beyond to make our visit to their venue a great time.
The Sunrise construction is not terrible, but you definitely notice it. The stores in Sunrise are closed so we were directed to the Nizuc gift shops to redeem our resort credit vouchers.
Should you be expecting your guests to have resort credits I would urge you to make sure all the reservations made through your group reservation have the promotion enabled as I know I had plenty of problems with that. Also, let your guests know to book spa/golf/tour reservations ahead of time. Availability is terrible once you're on site if you're trying to redeem your resort credit.
