I am not surprised that Celebrity is not more than Regent, but as I understand it Regent is more of a luxury line. Try comparing it to Princess, Holland, or NCL. As a solo traveler I can tell you that Celebrity is outrageous! In most cases if a solo was to book the AI option, which is now just tips and drinks, the price doubles or more than doubles and is way more than just adding the drink pkg and tips. They have pretty much priced themselves out of that market and created a lot of bad will along the way! Celebrity does not provide good value!
