I know not many people like them, but I sure do! Ive never been aboard her or her sisters, but I cant even imagine the spectacular view. Although it may not be for those with a a squeamish stomach. And Princess tried something different, and its just hit or miss in terms of whether passengers like it or not. She wasn't built as a liner, with classic lines in mind, but I do think she turned out stunning overall with her tiered balcony decks, the covered promenade that wraps around the bow, and yes, her "shopping cart" stern.
I know that Princess has removed the Skywalkers nightclub bar from the Grand Princess but as far as I am aware that is the only one. I had a cruise on the Star Princess and it certainly gave a great view.
