Without reading any previous comments, I have long believed that if the National came to West Palm Beach, FL, it might never leave.
There is a beautiful convention center in downtown West Palm, surrounded by hotels, and across the street from Ruth Chris, and a myriad of other restaurant and shopping options (Rosemary Square). That doesn't even include Clematis street, which is just a tiny bit further, and triples your options for post card-geeking enjoyment. It's also a 4 minute walk from the intracoastal, and 15-20 minute walk (5 minute drive) to the Atlantic Ocean. There are also a couple churches nearby if you're feeling religious.
It's a straight shot from Belvedere to 95 to Okeechobee, or Belvedere to Dixie to Okeechobee. You have the Brightline train that quickly can take you to Miami and back as well. Need I say more?
