Sloth related advice sought Myself and my girlfriend are going visiting Costa Rica in February/March 2018. We would both love to visit a Sloth Sanctuary and to see these wonderful creatures in their natural habitats. 
Are there any places that have sloths that we should avoid? 
Girlfriend is a radiographer, are there any ways she could use her skills to help sloths? (We are not brining diagnostic imaging equipment with us so this may not help.) 

Thanks in advance.
