Depends utterly on what you are looking for.
I notice you have DL in your profile, would I assume you would be planning to come in on the seasons JFK-Malaga service? Or are you connecting in?
Eitherway, what time does it arrive? Lets say you have 3 nights in Malaga, you have arrival day. Depending upon time of arrival, does this give you time in Malaga?
How would you be planning to move about? Train?
