Hey man, Miami is a fun city for sex and women. In fact I almost pulled a hat trick there a few years back, you can read the story here if you want a laugh and some inspiration before you go to Miami:

First off I assume your going to South Beach Miami? I personally wouldn't waste my time anywhere else. Stay at a Air BnB or cheap hotel off Collins avenue between 5th and 14th Street to get the best location for seduction. Uber everywhere you can't walk to. Hit up the clubs in the evening and hit up the beach and better yet the outdoor hotel pool lounges in the daytime to have some fun midday crowds.
My favorite venues in South Beach are:
Nightgame venues:
1) Story Nightclub: Big mega club, good venue layout. Make sure you find out in advance who's headlining the show there to get an idea of what the crowd will be like. You want to avoid hip hop shows as more black/thug crowd will be there. Definitely worth checking out if a electronic/house music DJ is playing as you'll get more hot white girls. Buy your tickets as far in advance as you can. I really like this place.
2) Liv Nightclub: Big mega club, I didn't like this place as much, same rules apply as above if you want to go when the sexiest people will be there. The cool thing about this place is at the end of the night when the club lets out there is a big lobby everyone lingers for a while and is a solid solid place to meet girls with lower guards up (since there light and no music playing) and pull them to an afterparty since they still want to party. Pro tip to save money: Sleep through the night and Set your alarm to wake up at 3AM and just wait in the lobby of the Fantainebleau (the hotel that LIV is situated in) for everyone to get out and skip all the bullshit in the club LOL.
3) The Delano: This is my favorite venue by far. Show up around 9:30ish after dinner and its a chill outdoor lounge with some really sexy women showing up to chill by the pool under the stars with good music.
4) Mangoes: You def need to check this place out even for just one night, just because its funny. This place is a trash heap fuck fest but its open till like 5-6AM in the morning and a cheap option to go meet some really cute girls after the main clubs close (or after you run out of money), just watch out for the war troll girls. This is a really good venue to pull from since its such a piece of shit you can easily have a good excuse to pull girls to go to your place for an afterparty. Here's a funny video RSD made of this place:

Daygame Venues
5) The beach - Lummus Park area - You can walk up and down the strip of the park OR go to the beach. Hot girls everywhere. If you not doing daygame in Miami your seriously missing out on a TON of opportunities for fun and probably some of the fastest daygame pulls you can get. Find girls by themselves and go on instant dates and pull them back to your place. Easy peasy.
6) Hotel Pool Lounges - There are a few hotels in a row that can be hit or miss for daytime action. The Delano, Ritz-Carlton Southbeach, Loews, and Royal Palm South Beach are like 4 hotels in a row that all can have really epic daygame spots. Just find a seat at the bar or near the pool and order a drink and chat up all the girls in the swimsuits... just make sure you dress appropriately for a sexy swim.
7) Lincoln Road Mall - If you need to go shopping for an outfit this is a good there are TONS of hot girls walking around the outdoor mall here. Not as good a place to pull from IMO but still a doable solid option. I took a few girls on instadates here.
That's the main gist of things in South Beach. Enjoy yourself man its a fun time there.
