My sister's husband wants to travel to Belize.
I have suggested he go with me and my family, and leave my sister at home. I know her well, and Belize is not for her, she would be miserable. She hates to walk, and is not a beach or water person, therefore just not enough shopping and such for her to fill her time with.
She has agreed, after I explained what a perfect vacation for me is like in Belize.
