We're planning an outdoor tented wedding. To save, my caterer suggested I should rent dinnerware (chinaware, silverware, glassware, ect.) directly from a vendor, rather than through them. If I do that, what is the average amount that I should rent for a dinner buffet and cocktails? Would I have to rent twice as much as the number of people attending? We're estimating about 120-150 people to attend. Any ideas? Thanks!
