Thanks for your contributions to my inquiry. 
Setting the Sydney aside for a moment, as for the Rising Star class - nice ship. While familiar looking it has distinctly different lines combining to present a softer, more nautical appearance. It would certainty work as a cruise ship class in the primeline.
Ah, as in the Jenolen. Butt ugly, and not very big, but yeah, could it be one of only a few options for civilian space transport? Could resources within the Fed have been stretched so thin so as to prohibit producing any thing resembling a luxury civilian liner? That could have been an [in universe] intention, or were the producers forced to give that impression because they couldn't afford to make anything better on their budgets.
I think the latter.
Again, lack of funding probably tied producers hands from really expanding the Trek Universe to visually match its potential.
In Universe, this suggests things were better earlier in the history of that timeline for civilian space travelers, (while still not as great as one might expect) and getting worse with the passage of time.
Reality probably was the producers had to make money stretch so, in universe, making resources within the FED scare served as a excuse to downsize the sandbox.
Timo, during my search for info on the Stellaford I found another thread about it on these forums which may have been a better place to bring up this topic, but I hadn't seen it yet. Transferring there now... Thread title: Stellarford class post 22

One thing I've had in mind ever since those hugh blimp-y looking things in the sky in ID is, could Starfleet (or a civilian agency) have and operate never before seen class(es) of ships for Tourism among Federation Worlds - Warp Capable Cruise Ships!
Surely the massive civilization depicted in NuTrek, and by extension, an assumption civilization exists on that scale and beyond throughout the Federation, would have need to travel between worlds for reasons of both pleasure and business.
Sure, Jackill's third volume includes such a design specifically (the Rising Star class liner), and the Sydney might also fall under the same classification. I think FASA might have had one or two civilian designs like this as well, but I could be remembering wrong.

We have often seen passengers travel on what look like military transports (the Sydney class vessels in DS9), but this need not mean there wouldn't be other types of liner, as well as cruise ships and the like. Then again, it can mean exactly that - perhaps Starfleet really controls everything relating to starflight?

Yet it is curious that we never get a dialogue mention of space tourism. Civilians traveling on liners or military transports always seem to be on serious business. Or then they travel to a specific resort, usually Risa, which is not quite the same as booking a cruise.

Really, the closest thing to cruise vacations is the Boomer lifestyle from ENT, with all the stories about strange alien ports. But it's not quite vacation, either, even if one might theoretically consider some of the family members "passengers" rather than "crew".

As for noncanon ideas, the old Spaceflight Chronology already had a cruise ship included. The Stellarford (nod to the illustrator?) is called a "starliner", but described as carrying "tourists" to "excursions" to "galactic wonders", rather than running a line in the traditional sense.
