This will be my third time. Have done Isla Mujeres. Took a catamaran over to the island stopped at a few spots to snorkel. Pretty fun time. I think Mexico City might be in that cards for a future trip, wanna do Rio and a European cruise before that though.
I lived in Sao Paulo for two years. Don't go to Brazil, you will never come back. It's that's nice and the women are the most beautiful in the world. Enjoy.
I'm sold. Was planning on going there this upcoming year but didn't know if i wanted to go to São Paulo or Rio.
