Nice video. I really wish you would have mentioned that the entire north end of Isla Mujeres is a NFZ. I just got back from there and stayed at the Mia Reef on Isla Mujeres. (The large private resort on it's own little reef at the northern end of the island). It was beautiful, but I was SOOOO disappointed that I couldn't fly my mavic anywhere at the resort because of the No Fly Zone. I did get some great footage of Point Sur, ( the cliffs on the other end of the island) - like you did.
I actually wasted 2 hours at an internet cafe on Isla Mujeres trying to downgrade my firmware to a lower version so I could fly at our resort - it didn't work, their internet speed was too slow or unreliable. The sad thing is that the reason it's a NFZ is because of 1 old runway that is still sometimes used by private aircraft. There is no airport - per se, just a single landing strip that was used exactly 1 time by a small private plane during the entire 8 days that we were staying there. What a beautiful place. I would probably go back in a heartbeat, but I think I'll need to find a different beautiful place where I can fly the mavic.
