grammaticality - How do I refer to joint possession in the second person plural for "you and X’s arrival"?

I’m about to send out an email and I’m unsure whether the sentence is correct. A friend told me the word arrival needs to be possessed by a person for the sentence to be grammatically correct. The sentence I intended to use is as follows:

I am looking forward to you and the rest of the parties' arrival.

Is this correct, or is there a better wording of this sentence?
