Pretty must all wedding etiquette I know I learned from this site. My question is on blocking hotel rooms. I have no idea about any of this. How do you figure out how many rooms you need? ( after STDs? ) Do I have to pay anything to block the rooms? How far in advance? If my guests decide to stay else where am I stuck with the bill? I plan on calling some hotels soon but didn't want to seem like an idiot on the phone. Hopefully you knotties can bring me up to speed. Thanks!
