Where is your wedding location? Just my opinion, but I would be offended if I got invited to a destination wedding and was not given the option to bring a guest. In all honesty, I would not attend. I would not pay that much money to go and not be able to travel with my significant other or a travel companion. I'm giving all my guest the option to bring one guest. However, I have a 19 year old cousin that said to me the other day that she has 3 friends that want to go to Mexico. I said "Sure, no problem, I wouldn't stop anyone from going on vacation, but you have to pick ONE of them to attend the wedding events and the other 2 can find something else to do for a few hours".
