One thing that Miami definitely does big are popular cruises. At any given time there can be up to 5 or 6 massive cruise ships docked at once. One of my favorite things to do is go swimming on South Beach around 3 PM on a Saturday and watch all the cruise ships pull out of the Port of Miami on their way to the Caribbean, it’s a pretty impressive sight.
If you drive by on Macarthur Causeway in between South Beach and the Port of Miami, you can see the people on the ships waving to the people driving by. Many of us locals return the wave and send them off on their vacations with a smile.
When you live in a vacation destination, I feel like you have to be an ambassador of that place, and even going out of your way to ask if someone needs help with directions, a good recommendation of somewhere to eat, etc. goes a long way and those people will remember their time in your hometown fondly. Pay it forward!
