Upgrading to 14,000 feet was absolutely the right decision! My first time in Guam and my first time skydiving. The only scary part was when we stepped out of the plane, but immediately afterwards, the view of Guam that you can only see from above unfolded before me, and it was simply an amazing sight. I thought it would be enough to do it once in my life, but if I have the chance, I would definitely do it again! It was an incredible experience.
