The hardest part of this glitch is getting the trucks into the right place! There was another way to get onto the hotel by using crates but we found this way is a lot faster and easier. Once we got up onto the hotel we had the idea of jumping over the barrier which worked and that's how we found this glitch. We have found another way to get out of the map which is an easier way! Once I post that I'll put a link here, where the video is in this forum, but for now here is one way to get out of the map Resort.
