OK, my comparison thoughts for those that are interested. I'll list which line I thought was better under each item.
PRINCESS (Regal) vs. Norwegian/NCL (Escape & Getaway)
Room at the End of the Bed
PRINCESS - Princess has almost double the walking space! We had a standard balcony cabin.
PRINCESS - The chairs were more comfortable to sit in - they had a higher back and were adjustable.
NCL - More spacious. You could easily change in the bathroom without feeling like you needed to step into the shower to do so. There was also more counter space.
Programming on the TV
PRINCESS - Loved the free movies-on-demand and programming such as the Wake Show & travel documentaries.
General Cabin Areas
TOSS UP - Princess has a much better layout for accessing the closet. NCL has a couch as part of their basic balcony cabin.
FOOD & DINING
Main Dining Room
PRINCESS - Princess offered entrees with shrimp, prawns, scallops, filet, lobster. These were offerings you really had to go a specialty restaurant on NCL to get. The food we had on Princess also had well-developed flavors, whereas on NCL we had a number of dishes that lacked flavor/seasoning, but were still very salty.
Other Included Food Options
PRINCESS - you have four options other than the buffet for food (and the International Cafe is fantastic!). While the pub-style restaurant on NCL (the only other included food option besides the buffet) had pretty good food, the location was loud and the service was spotty at best.
PRINCESS - Hands down. Princess had REAL cheesecake, and the other dessert offerings were very good. NCL desserts looked ok, but they all tasted a bit blah/gelatinous. (The desserts in the NCL specialty restaurants were very good, however.)
NCL by a little - all they offer is anytime dining and they just seem to have it down to a science. We only had a couple of nights on Princess where we had a 15 minute-or-so wait time - so it wasn’t bad at all. I’ll gladly wait a few minutes for better food. 😉
PRINCESS - pre-registering with the app made check-in a breeze. We literally walked right on the ship - no lines, no holding rooms. 15 minutes or less from curb to ship.
NCL - It was very easy to find your way around their ships. Princess had layouts that seemed “choppy” and I think that made it very difficult to get your bearings. We also missed NCL’s distinctive patterns on the carpet in the cabin hallways that let you know which way was forward or aft.
PRINCESS - There is just more lounge area & pool area when it isn’t taken up with rope courses, waterslides, climbing walls and the specialty suites-only area like on NCL. While the activities are fun, they do make the pool and deck areas much more limited.
NCL - they have a beautiful, spacious promenade deck with comfy outdoor seating areas all around. They even had seating for some of the restaurants and bars on the promenade. We did miss that on the Regal - while you can get outdoors on deck 7, the area is quite limited.
PRINCESS - not only is their Medallion internet much more affordable than NCL, it is much faster!
PRINCESS - the ease of finding your shipmates was as easy as opening up the app on your phone (or going to an interactive screen in the elevator area) and locating them via their medallion. This was wonderful when locating our teenagers, and made everyone's experience more relaxing and safe.
NCL - Their website for managing your booking/reservations/planning was much easier to log into and navigate than the Princess equivalent.
