Tips for Belize!

Looking to see if there are any suggestions all of you would have for me! I lived in Belize when I was born until I was 12 years old. I have not seen Belize in almost 10 years but I am coming for my honeymoon in Hamanasi Resort. After Hamanasi, I plan to stay in Santa Elena and San Ignacio where I was born. Anything I should try that I may have missed over the years? Any tips?
