If your invitation says “and Guest,” then yes, if not, we would prefer if it was just you.
No, the hotel does not have a shuttle service. But there are directions on how to get from the hotel to the church.
If the invitation says “family” then yes. There will be a kids room with a kids buffet.
Cocktail, please. But we want you to feel comfortable, so if those shoes are too high or that top button is too tight, let it all hang loose.
