Snacks
Now, for some people, not the most important thing, but for the right crowd this can play a vital role in the epicness of this trip.
Plan for different people, so vary your type of food so everyone can find something they like. Try and keep your snacks ranging from proper foods and different little foods so that you can satisfy your hunger. If you want to make double sure, check in with your friend beforehand to see and make sure what type of foods they like.
Make sure to add a few big fun things:
You are going to do a lot of things on your trip, but try and plan one or two bigger things depending on the length of your getaway.
Try to keep the entire event peaceful and relaxing
I know that some things on a trip might not end up how it was planned to work out or some inconveniences might occur , but tray and keep the peace between all parties. Now I also know that this seams way easier than it really is an can also be very exhausting , so try and get a few easy ays to solve some common problems (not agreeing , not wanting to , ect.).
