When does NextCruise desk open on embarkation day?

Boarding the Silhouette next week and want to book one of the new itineraries. IS the NextCruise desk usually open on boarding?

Last time we were ready to book as we got on the Future Cruise Office opened at 3.

Usually after the boat drill.

What are the advantages of booking on board? We are sailing June 1, but also looking at an October cruise.

Any information would be helpful.

In the dailies they publish the hours of operation, last Eclipse sailing 12 noon to 8 PM, closed during the drill.
