Yes, the Conquest does a sail-away party. Mostly on the pool deck and spa deck. It starts after the muster drill (life jacket drill). But, I'm not sure how much I consider having to buy my own drinks as a "party". Typically the cruise director will be there and give a couple of welcome aboard type annoucnements and there is a band and such. If you want to be on the Cruise Log video, then show up and find the guy with the big video camera, he will be there taking shots for the DVD.
Normally we have early dinner seating and by the time muster drill is done, you have a few minutes of time to see the actual sail away before you need to be down changing for dinner. If you want to enjoy the party longer, dress for dinner (relax requirements for the first night anyway)and then you can hang out until dinner time.
You'll have a great time. The Conquest is a great ship.
