Just wanted to post briefly.
I found the strategy posted in this thread is actually much more difficult than the one I used. The only way to win this (well maybe not the only way, but the most effective way), is to build a tourist industry from scratch, without going through the usual route of building somthing else to finance it.
The difficulty is that the way the board is set up decieves you into thinking you should expand towards the spare dock near the cannery. But you can't get down there without chaining construction offices down the coast until you can build a tenement down there to get workers to move to that area, and build up a town.
Unfortunately, you don't really have enough time to do that, and you need a source of money to finance the process, which diverts you into attempting to build up an industry.
What I did is to immediately build a cheap hotel on the coast near the airport. By putting it on priority, and forcing workers to fill the construction office, I was able to get it and the diplomatic ministry built with the initial funds. I set all the farms to sugar, shut down the cannery, extra dock, and fishing wharfs, and set their maintenance to "back to the sea". The sugar sales gave me an early infusion of cash that allowed me to then use the trade delegation to get an aid package, as suggested above.
With that money I built a beach site and pub, which got tourism off the ground. Then I built a cattle ranch and logging camp since I was going to have to turn my farms off of sugar, sicne the people were starving. I also built a construction office over the hill and another to the south.
By this point, the soil conditions had improved so I could switch to pineapples, which kept my people from starving, while the ranch and logging gave me a steady enough cash supply to start expanding a tourism industry along the coast by the airport.
I found that even building a lumber mill was counterproductive though.
As soon as the construction office on the other side of the hill is built, add a tenement next to it to house the workers so they don't have to walk as far. Then build a hotel on the nother coast. Keep using the diplomatic ministry to get extra money, and occasionally, skilled workers. The building subsidy is also good.
Once you can get a hotel built (conditions on the other side of the road that runs diagonally north of the airport) then the tourism industry becomes the main source of cash, and you can build a large tourist region on the other side of the hill. Ignore the southern dock and just use the airport to bring in tourists.
As soon as the cattle ranch and logging camp start producing income, use the funds to build a school and college, which will supply workers for a church and clinic, and keep your people from revolting. I rigged every election so that their liberty wasn't too low, but I didn't waste money trying to make them happy. Build tenements and apartment complexs to house them, using the russian development aid.
After building two hotels, a restaurant, and a couple more beach sites, the cash started really rolling in, and then I could use it to rapidly build a huge tourist region, with electricity, a luxury hotel, conservatory, gourmet restaurant, etc. It takes a lot of hotels to get 100 tourists, and it's hard to get a rating of 60 without buildings that use electricity, so you should also build a power plant as soon as the tourist revenue starts really flowing.
I think this is a really tricky scenario, which is cool, because it forces you to get a feel for how to build a tourist industry from scratch. In the end, the things that seem to be harder are actually easier.
