Just my 2 cents, but I'd head to Maui
Been to Zihua and Maui and I'd pick Maui no question. I love Mexico more than anything, been to Playa 6 times and would live there if I could, but Zihua just didn't do it for me (just my 2 cents, I know lots of people love it there). Maui was so beautiful and we had the time of our life there.
