My friend told me about ambucare-there located allover the island-but are not stationed in Negril…none--the less they are more what you expect a professional ambulance to be and their website says they take debit/credit cards..

You can email them and ask about response times to negril and costs…..heres their website www.ambucareja.com and their mobay # 876-953-2938
I would hope someone who lives there would know what private ambulance is used most and would respond to your question…
