Oooops, sounds like Phuket is beautiful but incredibly frustrating to navigate! Insane how places explode in popularity, but no infrastructure seems able to keep up. Chalong Circle must be a nightmare: five major roads converging on that one spot? Ugh! I totally see why you will appreciate Da Nang more after this trip! It's so interesting how the freedom to travel would not always mean you want to do so. At times, there are hassles that surpass the joy, especially when it's already a battle just getting point A to point B. Good to know you got to catch up with your friend! But I shall totally not blame you for wanting to chill on your last day. Enjoy your return to Da Nang, sounds a lot smoother!
