Emporium
I have done one sailing on Explora and will be going again in October.
I know this may shock some people but I don't love the Emporium, especially for dinner. I find it to be too busy and the seating feeling too close to the activity for it to be relaxing. I did use it a few times at mid-day but never warmed up to it for dinner. I hate having to get up multiple times to get different thing.
Any secret place where it feels quieter? I found the outside seating to be the best.
