Shorts, tank tops, and sun dresses: If you are traveling during the warmer months, make sure to pack outfits that are light and comfortable because it can get very humid and hot during the day.
Cardigan or light sweatshirt: Since temperatures during the summer months can reach into the 90s or 100s (Fahrenheit), restaurants and inside attractions will really crank up the AC to keep you cool.
Waterproof walking shoes or sandals: No raincoat, umbrella, or poncho will be able to keep your feet dry, so I recommend bringing a good pair of walking shoes that you don’t mind getting wet.
Nice sandals or flats: If you’re going out to dinner or bars and want to dress up a bit, a nice pair of sandals or flats will work for most dressy outfits in the hot weather.
Plastic poncho: I prefer to bring a cheap plastic poncho with me instead of a raincoat or an umbrella. It’s won’t add extra weight or take up too much space in your bag, and it won’t retain too much heat in the summer.
Camera: You’ll want to take a lot of pictures in the theme parks! I usually just stick with my smartphone camera, but if you are big on photography, there are so many great moments to capture on this trip so you’ll definitely want a good camera.
