I too am interested in starting up a hostel or lodging in South or Central America and am actually doing some location scouting soon. I am interesting in working with others who have similar ambitions, such as yourself. You say you are looking for a 50% partnership, do you mean and as a principal managing partner or financial/investment partner? Do you have any relevant qualifications or experience in undertaking such an endeavour? Please feel free to send me a message, I look forward to hearing from you.
