I'm not sure where you're from, but for people from the US, there's a pretty strong travel advisory due to the unrest in Haiti:

Travel is hazardous within Port-au-Prince. Some areas are off-limits to embassy staff, including downtown Port-au-Prince, after dark. U.S. Embassy personnel are under an embassy-imposed curfew and must remain in their homes or in U.S. government facilities during the curfew. The embassy limits travel by its staff to areas outside of Port-au-Prince and therefore the ability to provide emergency services to U.S. citizens outside of Port-au-Prince is constrained. The UN stabilization force (MINUSTAH) remains fully deployed and is assisting the government of Haiti in providing security.

Due to the current security situation in Haiti, the Department of State reminds U.S. citizens traveling to or residing in Haiti to remain vigilant with regard to their personal security; they are strongly advised to register either online at https://travelregistration.state.gov/ibrs/ or with the Consular Section of the U.S. Embassy in Port-au-Prince.

I don't think that Haiti is, as yet, a poplular tourist destination....

In no way shape or form, do we encourage anybody to vacation in Haiti. Aside from any of the other problems, Haiti does not have the infrastructure for mass tourism, at least at this time. However, the fact can not be denied that there is a small percentage of people who are interested in visiting Haiti. I've seen many tourist in Port au Prince, Jacmel, Cap Haitien, and Petionville. Therefore, this site is for those people who are interested in visiting Haiti.
Again, in no way shape or form do I encourage planning your Caribbean vacation to Haiti.

I'm sorry - you were asking if tourism is increasing, I was just saying I don't think it is due to the concerns of traveling there - and if they're not traveling there, new hotels won't be built.... I didn't think you were suggesting people go there - sorry if you thought I meant that....
