When the object of a preposition is a pronoun, the object form is required.
For this example, we use the pronoun "them" because it is in the predicate of the sentence and is the object of a preposition. Note: "Them" in this sentence refers to the guests, not the bride and groom. 
The pronoun "them" is used to refer to more than one person or thing when they are the object of a preposition. In this case, the bride and group are the objects of the preposition "of" so we would use the plural pronoun "them" in this instance. (Prepositions are words that link other parts of speech from the sentence together. Some common prepositions are: in, out, above, below, of, toward, to, by, etc.)
The pronoun "they" is used to refer to more than one person or thing when they are the subject of a sentence. You can ask yourself, are these people or things the ones doing the action in the sentence?
The pronoun "themselves" is a reflexive pronoun. Reflexive pronouns are used when the subject of the sentence and the object of the verb are the same person or thing. Examples: I couldn't believe I didn't cut myself with that large knife; She was nervous about swimming by herself for the first time. In this case, the bride and groom are the subject, but the pronoun refers to the guests so you would not use a reflexive pronoun.
The pronoun "their" is a possessive pronoun that is used to show ownership. In the case of "their," it would be used to show some sort of ownership. In this case, the bride and groom are giving something to their guests, and does not require a possessive pronoun in that spot.
