@Stem to Stern did a Live From review of the Summit a few months back (later 2023, I think) and he was in the Retreat. Photos and his account of the cruise made me want to book the Summit! I would pour through some Youtube videos for recent tours and reviews. Since the ship has been refurbished, I think it looks very classy and upscale. Though I haven't pulled the trigger on a Summit booking, I haven't ruled it out for the near future.
