This year the Brightline is finally running and a great option to get the Miami International without sitting in traffic even if you live all the way in Palm Beach. Tickets are around $25 over the weekend if you use the Promo Code "GOSMART" you will receive 25% off your fare.
Here are the links for where you can get on the Brightline :
Once you make it to the Miami Brightline Station there will be a complimentary shuttle to take you to the Miami Boat Show it states on their website it should take about 15 minutes.
Really great option to get down to the event cause we all know how Miami traffic can be if you don't want to take the shuttle Lyft & Uber drivers will be at the station as well with a designated pick up zone.
