Yes. You can decide to give everyone two favors or give half the guests one favor and half the other. Splitting the two favors among your guests may save you money since you’re buying one per guest total instead of two items for everyone.
But before you order either figure out if one can be used in another part of the wedding. For example, would one item work well in a guest room gift bag? How about as favors at the rehearsal dinner?
If you’re not adamant about it, let your fiance have the favor he wants -- how many things has he asked for anyway?
