I stumbled across an American forum (for those interested, finish the phrase 'tying the...' .com) - I'm bored at work, sue me.
I can't believe how rude and ridiculous people are. According to the Americans, things that are no gos - inviting ANYONE to the reception that wasn't at the ceremony. Not for dinner, not for drinks. Having a cash bar - you either pay for ALL their drinks or don't supply alcohol at all. Having a wedding reception on a day other than your wedding - it's just a party and you can't relate it to the wedding at all.
So many people are being shot down on it and it gave me the warm and fuzzies that we're safe here....
