Totally reasonable to ask - I meant to include our background. Our favourite lines would be Crystal (soon to be resurrected, we hope!) and Regent. We have also sailed with Celebrity and Disney and would view them as different, so would not compare either, meaningfully, to Silversea or the others.
We enjoy musical theatre and popular music revue shows (brilliantly executed by Silversea) and live music around the ship, both in the daytime and before and after dinner, which was less of a strength for them.
