the key to this it to not freak out and to not worry about it too much. just think about the goal you want to reach. you want to become friends with all these cool people and meet lots of hot guys! the only thing stopping from reaching this goal is yourself. it might be so scary and nerve-wracking putting yourself out there and talking to random people, but it will be totally worth it because you will have overcome this fear, and will be able to hang out with them and totally be able to relax around them in like a day haha. so don't worry too much just be outgoing, be confident, have fun, and be yourself! also, if you meet one person, you can go around with them to talk to more people, so it isn't at scary. also, you are more than likely not going to see the people from the cruise ever again, so just do it! don't have any regrets!
