Often there will be quite a few guests who choose to pass on the wedding cake that is offered to them, so you can take this into account, be careful not to undershoot your estimate though.

Another option is to have a display wedding cake made that only actually consists of one layer of real cake and the rest can be a fake cake. You can keep a large slab of cake in the kitchen which can actually save money and your guests probably won’t be able to tell the difference,
