We are going the all-inclusive route. Flights to turks and caicos are expensive enough, so at least all the drinks and food and certain activites will be included.
Roses are generally on the less expensive side....im scared to know what they would charge for anything else!! Here is a link to a flower finder....hope this helps! http://www.sierraflowerfinder.com/
Oh,and if your dying for some color, have them wrap your bouqet in some color ribbon that will match your girls, thats what i do at work (floral designer) for our brides!
I like the white and green.....I love colored boquets, but sometimes against a white dress that is all you see is this big ball of color, so for me the white and green is the winner, more romantic!!!
