We are having a non-alcoholic wedding. Instead we are planning on doing a self serve coffee bar, pop, water, and a few non-alcoholic mixed drinks if possible. We are looking for ideas on how to make sure people are getting their drinks but unsure how to have them served/out for people to get themselves without a bartender. Our reception is not anything very fancy but we would also not like to have getting drinks difficult or create a mess. Any suggestions would be greatly appreciated!
