Plus ones are not permitted unless we have approved them due to needing an exact amount of RSVPs for catering.
Of course you can!! The only thing I will say is that they are not recommended once the reception starts as there will be partying and drinking.
While it may not be expected, we would greatly appreciate if everyone donated to our honeymoon fund! We don't need any physical gifts with how long we've lived together so we will have a card box at the reception and there will be a QR code for our cash app/venmo!
