Okay, I've now done some in-game looking-at-numbers, and the Manual is wrong. Very wrong.
None of the tourist attractions can be built without a tourist accomodation building first. The in-game gives me the impression that it doesn't matter what kind of hotel I build, but I have not tested this.
Four entertainment buildings can be built without Electricity. In addition to the 3 from the list above, Childhood Museum, Pub and Restaurent (non-Gourmet), the Cabaret can also be built without electricity.
Here's some analysis
Building Cost Cust C/Cust Workers/t Quality Upk/Y Upk/m Wage/m Total/m DChar RChar
Pub 800 8 100 2 35 24 2 10 12 5 ?
Restaurent 2000 8 250 2 40 48 4 10 14 5 ?
Ch.Museum 2000 / 6 / 330 2h 40 60 5 20 25 5 ?
Cabaret 4000 9 440 3 62 156 13 15 28 10 ?
All workers must be female. 2h means 2 high school-educated (females).
Wages are based on the default 5/10/20 education level-dependent wage scheme.
Pub and Restaurent can handle 4 customers per worker, Museum and Cabaret 3 customers per worker.
Note that the Childhood Museum's default setting is Loudspeakers which makes the visitors respect (yay!) you more. The alternative is something to do with Swiss Banking.
The three other (pure entertainment) buildings have 2 or 3 settings that alters the quality level but may exclude lower-class Tropicans, or alters the quality level but affects upkeep.
What puzzles me is, why ever build Restaurents? They cost a lot more to build, per potential customer, but the quality is only slightly higher (12% higher), compared to a Pub. One could speculative that Tropicans have different preferences for entertainment, so that some might prefer a Pub, and others good middle class food, but I'm unconvinced that this is the case, due to having read a few threads on this forum.
I'd thus be disinclined to skip the Restaurent entirely, and build only Pubs and Cabarets, and maybe one or two Museums too, mainly in order to increase Respect.
Upkeep is irrelevant when compared to the high wages of a fully staffed entertainment facility, so wage is what counts. Default Charge is 5 for the first three, 10 for the second, but I'm not at all sure exactly how Charge (entry fee) works (i.e. does a Tropican actually pay 5 dollars to enter a pub? - I kinda suspect he does not), and therefore I cannot recommend a charge. The default ones are probably good, although if you toggle quality level, you should obviously change charge. And maybe make the museum cheaper because you want as many Tropicans as possible listening to your Respect-increasing loudspeaker propaganda.
Another approach is to look at the building, a few years after it has been built, then adjust the charge based on how profitable the building is, i.e. if it's running at a loss increase the charge or fire one of the workers (thus significantly reducing the running costs), or if it is making a huge profit, reduce the charge, since the primary purpose of the building is to make Tropicans happier, with making a (small) profit being only a secondary purpose.
I never did look into Entertainment buildings while playing Tropic 1+E, I'd just plop down a few, eventually, because of massive clamouring, but this brief analysis has given me a little piece of mind regarding playing the game. I have a better idea, now, of what to build, and when and where.
edit notes: Skype inserted some crap formatting that mucked up my table, so I had to insert the forward slashes in order to get rid of the crap formatting. Anyone know how to get Skype to not do that?
