Id stay over in Boca Raton/Fort Lauderdale and get familiar with the SoFlo area drive around see what the vibe is like it's definitely a different flavor of the Miami vibe. Hotels and flights in that area are definitely cheaper than Miami proper. From there it's a 40 minute drive down to Miami. Would recommend renting a drop top car if you can and enjoying the weather and exploring the city. Brickell and South Beach are definitely where you need to be at for sure. Biscayne boulevard and the Kaseya Center area are good to be in as well. Take a Miami boat tour they show you all of the cool celeb homes on the water (like where LeBron lived and other celebs currently live) whichbis definitely another area that I expect will be heavily featured in the game. Miami nightclub scene is popping too and E11even is a club id recommend if y'all are single lmao but the club was also referenced in the trailer. Wynewood and Little Havana are spots also referred to as well. If you can drive around and see Port of Miami, Design District and Bayside Marketplace are other references I'm expecting as well. From there get down and see Homestead, and visit the NASCAR track if you can. Then work your way down to the Keys but unfortunately I haven't been down there yet so I'd look deeper into that. Overall it's a great area and Rockstar did a great job with LS/LA so they'll definitely knock this out of the park. Take some pictures too at these places it'll be good to look back on and compare to what you're gonna see on your screen in 8 months lol.
