I was actually surprised at the price difference between an ocean-view balcony and an interior-view balcony. The verandah with a view of "Central Park" is only $998 per person, but the ocean view verandah is $2,124 per person! I went with the ocean-view verandah in my comparison because that's the most similar to Disney's verandah rooms.
I'm writing about NCL because I'm more familiar with their policies. The soda package is $9.95 per person per day, plus a 20% gratuity. In total, that's $11.40 per person per day. I would have to drink
four sodas every day to break even on that package. And, I have to purchase it for everyone in my stateroom, so we would
each have to drink four sodas every day to save any money vs. just paying $3.20 for a soda. So, no, it isn't very cheap.
As for the adults-only area, NCL has Spice H2O for free and Vibe for quite a lot extra. NCL says of Spice H2O:
"The idea behind Spice H20 is based on a typical adults-only beach party in Ibiza, Spain. In other words, you can party it up here until your heart's content. The outdoor Spice H20 venue on Deck 17 comes complete with tiered lounging areas, hot tubs for relaxing and unwinding, and water features for cooling off. What's the bonus here? Without any kids, Spice H20 is a calming choice over the busy pool deck. At night, this transformative space becomes one of the trendiest nightclubs on the Norwegian Bliss where you can dance underneath the stars while watching the giant video screen."
So, sure, it's quiet for part of the day. Reviews say that it's always crowded, that there's very little shade, that it's sometimes hard to get a chair, that the chairs aren't padded, and that smoking is allowed on one side of the area, which tends to drift over the rest of it. Also, it's loud at night because it turns into an outdoor nightclub. Or, you can pay extra for something more similar to Quiet Cove.
Here is Carnival's example dinner menu:

Notice that the only steak options cost $23 extra. There is no free steak on that menu. A filet costs $23. Even strip steak costs $23. So does lobster. All of those options are free on Disney cruises.
Maybe RCL is better. I never said anything otherwise. I made it very clear that I was talking about NCL (and later Carnival) when I made my initial comments about price differences.
I've mentioned before that I have an upcoming cruise on NCL in the spring. I'm trying to look forward to it. I really am. If nothing else, I'll at least enjoy the night in NYC before the cruise!
Yeah... NCL has one "Broadway-style show" and a 30-minute dance show. RCL seems to also have one "Broadway-style" show on their cruises. Nothing like Disney's 2-3 shows plus variety acts.
