I just read a thread from a few months ago where a girl asked how to go about inviting people to just the dance and not the dinner and I have to say I was surprised by how many people are against it! I am inviting a handful of guests just to the dance because there is just no way to fit them in my "dinner" guest list(believe me I tried over and over again).
I am also so surprised by how many people are against a cash bar! We are only serving free beer and if the guests want anything else they can buy it themselves, im sorry but I can't afford to buy alcholol for 150 + people. I personally think its rude to expect an open bar.
I just have to say that while there are some traditions to follow and maybe there are some etiquette rules to follow also, this is my wedding and who is to say what is right and what is wrong? I don't want one day of celebration to put me into debt for the next five years just so I can please my guests. I say forget the rules and do you.
