21 days? This was be the Panama Canal cruise I was looking at for 2022. However, I went with the L.A. to Miami on NCL Bliss because it was a Megaship with a reduced capacity of 1300 (vs 4000). I wanted to experience a big ship without all the crowds. I forgot how big RSS Mariner's Penthouse are (albeit small bathroom and balcony). I am looking at voyages aboard Regent for 2024-2026. Thanks for the video (two years later)!
