I made dining reservations months ago for our trip in March 2013. My son and his girlfriend decided to join us so now some of my reservations are short by one. (We thought my son might decide to go...didn't expect the girlfriend) We really want to eat at these places (Ohana, etc...) What will happen if we show up with one extra person? I tried to change the reservations but no space available. Two of the persons eating with us are employees of WDW. Can I contact the restaurants directly and see what they advise. The dining reservations people says they can't help us. Any advice?....
