I am a planner when it comes to big trips like spring break, so I have been planning all the things I am going to bring for weeks. I think that I have a couple of items that you might not have thought about.
For starters, I would recommend bringing a first aid kit, while this one will hopefully go without using, but its always good to have it in case of an emergency. You never know what could happen when alcohol is involved and if your friends are anything like mine our luck is not always the best. Especially when crazy drunk boys are out having a great time on their spring break. I truly hope that you and your friends on the trip will not have to use a first aid kit and your trip goes smoothly without a flaw.
Bringing groceries beforehand is an easy way to save money. I recommend going to the grocery store before you start the trip or somewhere along the way to get there. I am not saying you can't go out to a restaurant during spring break, but as a broke college student, I am willing to save money wherever I can. It also helps because you know exactly what you are getting so you can get the food you enjoy. Also, when you've been busy all day you might not want to leave and go out somewhere.
A speaker is always a great idea! It doesn't matter where you are going for Spring break, bringing a speaker is an easy way to make sure you have great music on blast. You can bring a speaker outside or have it going in the place you are staying, just make sure it is waterproof.
Who knows what the days have in store on spring break, I recommend bringing a portable charger. Spring break comes with long days of having fun with your friends you don't want to worry about your phone dying throughout the day.
There are plenty of other things that you should bring to have the perfect spring break, but I am just saying these few essentials that most people including myself usually forget to pack!
