Hey there amee,
I'm actually thinking of doing the same for the reception site. I read somewhere on here that if you do order flowers or chair covers/sashes for the ceremony, they transfer everything to the reception site free of charge. I was thinking of adding some decor of my own to the reception, but I don't know how difficult it's going to be to a.) transport it to Jamaica and b.) have someone set it up for me the way that i want. If you find out any more info about home decor places, be sure to let me know.
