I've been to Hacienda Napoles (Pablo's estate where the hippos - and zebras, and rhinos and pretend dinosaurs with fake roaring speakers are). There are hotels you can stay in there ( I did not - I stayed in Doradal the nearby city with schools and hospitals built by Escobar). But if you stay in the park you must be in your hotel by 6pm say signs posted everywhere - because the hippos are nocturnal. They stay in the water all day and come out and ...roam and potentially kill at night. I stood for an hour with my toes in the water watching the hippos swim and I fed Vanessa - that is Pablo's pet pigmy hippo who is 'tame'. You buy (for about $1) a tupperware of carrots and celery and feed her. She let me scratch her nose. All of this is to say, Colombians on the ground where the hippos are spreading from have worked out ways to coexist with them.
