When planning a trip with a friend, there is a lot that can happen. You can fight over what activities to do, you can argue about the money you are spending in hotel rooms, you can distance yourselves from each other because of the awful time you shared during said trip. But it can also have a positive outcome: you can grow closer because of the trip bonding, you can learn more about each other, you can discover that going on trips with friends is the best way to spend vacation. That all depends solely on the attitude all of you have during the trip. How you compromise and communicate, trying to maintain your tones and have the best time together you can possibly have.
As someone who LOVES friends' trips, I can give you a bunch of reasons why they are the best kind of vacation you can get. But if you have the wrong attitude, then they won't work. I have gone on trips with friends, and it's important to keep in mind that you are going with people you like, people you care about. So, no matter the situation or the frustration you may feel, remain civil and kind. You don't want to fight and argue for days. You want to spend a nice time with amazing people. A lot can happen on a trip. Try to let the bad parts slip in, and the good parts become the main memories.
I remember that on my last trip with friends, we argued because of the condition that the apartment we were staying in was in. The place was great, but we were leaving dirty plates in the sink and clothes on the floor. It made me crazy. Instead of confronting them, I did something better. I started cleaning and kindly asked for help. They all pitched in, and in no time the place was looking great. So, don't be like the people from the story. Talk to your friends. You will probably find a solution where we all get what we want. And if not, maybe they aren't that good of friends.
