If you go with chairs that the Westin has, they will not charge you a rental fee. They can cover them in white and will add a bow. They tell you your color options to choose from. The linens are also included if you select from their color options on site. I did pay $100 for a white runner, $50 per dozen rose petals, and $8 per person for the cake. The cake price depends on how many people and what your dinner selection is. I paid $610 for a chuppa with flowers but it depends on the amount of flowers you want.
Hope this helps. If you have any other questions, please let me know.
