If you're booked with American...

I have a four-hour layover in Miami, too. There are worse places to be, but time is money!!!

There should be a mojito bar near your departure gate at the Miami airport where you can waste a few hours. We had a long layover there for our last trip and were feeling no pain whatsoever when we boarded our flight to Montego Bay.

I've had more than my share of 4+ hours (up to 8+... all AA flights) of layovers in Miami the last 10 years. I can't think of worse places. (My nickname for MIA is hell.) I purposely booked to AVOID the 4 hour layover. AA took that choice from me, again. Not thrilled. The later arrival really irks me. I can wile away hours w/ reading but would much rather be on my way to Jamaica.
