There's no guarantee the 5th guest would be permitted to dine with a reservation for 4. Your 4 top table would not accommodate the extra person so you would need a bigger table. You can call to see if Disney can help but your best bet is to continue searching for a reservation for the correct number in your party.So I have a BOG dinner reservation for 4 and now need one for 5!! Do I just keep checking for one for 5? If you have an extra guest will they still let you in? Or do I call Disney and see if they can help?!? Thanks- I would hate to miss out.
