Since when does Europe include "drink packages, refundable deposits..." as you wrote? Regent and Silversea are truly all inclusive lux lines, so there's only two prices. With air or without. Try calling Regent and ask them to quote price without drinks, wifi, and excursions and get back to me.
I never wrote that and it's completely unfair of you to infer that from what I wrote. You're totally out of line. Mandatory charges (taxes, port fees) should be clear. What I find foolish is your suggestion that the main display price should include things like drink packages, etc.
