My advce: Stay in Negril...Ochi is not "where it's at".
LOL....Ocho Rios is located in the GARDEN PARISH, surround by green lush vegetation and embraced by waterfalls. In one moment you can experience the not only the poverty the island is known for but the amazing beauty and wealth.
Depending on what you are seeking every destination in Jamaica is "where it's at". Negril is where the longest stretch of beach and cliff 'is at'. Montego Bay is where the airport 'is at'. Ocho Rios is where the lushness 'is at'.
