I was looking as a Azamara TATL for spring last year but fortunately never got past the had-a-look-at-the-prices stage.

The older ships are from the Renaissance fleet. Most had been acquired by Oceania and Azamara with the one of the missing sister being the Pacific Princess which was recently sold to Azamara so Azamara and Oceania now both have 4 each. Standard cabins seem to be a little small as it was not build to be a suite class ship.

It's not "all-inclusive" like RSSC but better than even a premium mass-market line (at least pre-COVID). Maybe like Oceania where you are not nickeled 'n dimed.
