Most couples brief a decorator or floral stylist with a mood board, then receive a proposal itemised by area: personal flowers, ceremony arch and aisle, reception tables, lounge corners, signage and lighting. Many Bali decorators own their furniture, arches and props, so the quote often bundles hire, set-up and take-down. Hotels and resorts may have in-house florists or a list of approved suppliers, so check the venue's rules before you sign.
Local tropical flowers, orchids and foliage are good value; imported roses, peonies and hydrangeas cost several times more and depend on supply. As a guide, a bridal bouquet starts around IDR 1 to 2.5 million, an intimate ceremony and dinner setup from about IDR 20 to 60 million, and full décor for 100 guests from around IDR 100 million, with luxury installations well above IDR 250 million. Sound and lighting sets hire from about IDR 3 to 11 million a night, and tents, dance floors and furniture are priced per item.
Book your decorator six to twelve months ahead for dry-season dates, and confirm the final design, flower list and colour palette about two months out. Plan a wet-weather version for outdoor ceremonies from November to March, including tent or canopy hire.
