Being the adventurous type I have (mostly) enjoyed and followed this thread so thought I'd add my 2 cents. First let me say kudos to you MoJo for keeping your civility in the face of naysayers and denigrators, you are a welcome member of the community and I wish you the best in whichever endeavor you choose in this phase of life.
The DR is indeed a beautiful and diverse country, and if people had seen what I have they would certainly want to explore more and stray from the AI that most park at while there. One member here, Cobraboy, had a business (not sure if he's still around or the biz is still up) which took people on motorcycle tours to various parts of the country and it always seemed a great business model to me. If advertised and marketed to the right demography I'm sure something like you envision could be done, certain people are always looking for a different type of vacation/adventure.
Most people who camp are either young or have their own RV, thus most is done in their home country. As many have stated comfort and safety while in another country is important. It is one thing to pack all you need into a vehicle, drive for miles to the beach/mountains, and visit a park or campground. Doing these things by flight is a whole new ball game

While I understand all these amenities can be provided it takes a certain amount of enjoyment and adventure from the process.
In order to offer this as a full country immersion would be a logistical nightmare. You would need transportation for large groups, camping gear for each location or more vehicles to haul gear, people to set up, etc. I understand and admire your objective to employ young disadvantaged folks for this but supervision, translators etc. would be a must, even if done locally and not on a country-wide scale. And security if not in a very isolated and secret place would be imperative, unfortunately.
In my late 40's and 50's I had an inflatable kayak I would vacation with but never took it to the DR . If I had known what I know now I would have vacationed more in my early years with one, paddled the coasts of places like CR, Mex Belize etc. and camped on public beaches, no problem. Sweating in a tent with a young companion would have been more fun

Now more into comfort but still like adventures lol. Best of luck again!
