My parents are giving us a very generous amount for our wedding that normally should cover all cost. Unfortunately my fiancée parents keep adding people to the guest list as well and things we need for the wedding (special meals, chuppah, personalized ceremony pieces etc) It's just too much. Our budget it close to going over at this point. Also we did not factor in the rehearsal dinner as he claimed his parents would pay but now they act like we have to just magically add it into our budget. The wedding is interfaith so we do have a lot of extra expenses in terms of ceremony pieces. How can I stay under budget without going crazy?
