A 150 person wedding in Washington is a large event requiring coordinated venue and vendor planning. Washington state's Seattle and wine country markets produce above-average costs, especially for summer and fall peak dates. With per-guest costs near $275 and fixed costs around $17,000, total estimates range from $49,513 to $66,988.
At this scale, a day of coordinator is standard practice and a full service planner is worth evaluating seriously. Coordinator fees typically run $1,500 to $4,000 depending on market and scope, and represent a small fraction of the overall budget. The value comes from managing 12 to 15 vendors simultaneously on the wedding day itself.
