How much for bus/flight/train to Miami

How much for bus/flight/train to Miami?
I live in NYC and I'm wondering which method of transportation would be most efficient to take. Both cost efficient and time efficient. Which do you recommend? I would be going around April. How much would this cost as well? Thanks in advance!

Greyhound Bus = $130.00 and the travel time is 1 Day, 8 Hours, 10 Minutes https://www.greyhound.com/home/ Amtrack Train = $471.00 and travel time is roughly 28 Hours (1 Day, 4 Hours) http://www.amtrak.com/servlet/ContentServer?pagename=Amtrak/HomePage Flying/Airplane = $317 and travel time is between 4-5 hours. http://www.orbitz.com/App/Home?reset=true&z=49d2&r=dv All the methods listed above are round-trip and I put a departure date of April 11th and a return date of April 18th. I don't know where exactly in New York your coming from so I just put the airport as JFK. As you can see taking the plane would be the easiest and the 2nd cheapest aside from the Greyhound Bus. The Amtrack Train isn't even worth it. It's a waste of time and money. The Greyhound Bus, from my experience, shouldn't be taken on such a long journey. I took the Greyhound Bus from here in Miami to Tallahassee in North Florida and it was decent but long. It took nearly 8-9 hours to get there and the bus is very boring. Just take the plane it's much easier and it will save you time and hassle.
