If your invitation says "and Guest", then yes. Please RSVP yourself and that special someone (or children) before RSVP deadline.
Cocktail, please. But we want you to feel comfortable, so if those shoes are too high or that top button is a little too tight, let it all hang out (respectively).
Yes, on the tab listed as "TRAVEL", you will find hotel blocks, airport recommendations, etc.
Unfortunately due to the venue change, we had to make some changes. Not everyone will be able to attend the reception but everyone is still invited to the wedding.
