Kona @ Poly & Boatrights @ POR... if your looking for something in the parks the MainStreet Bakery in the MK is wonderful, seating can sometimes be difficult but there are seats outside and you cant beat the view!
I would recommend making adr's. Things usuall fill up closer to your departure date. There has been times that we waited and coudn't get in depending on the time of year you are going. I am leaving on Friday for WDW and made ressies about three months ago to assure I would have them. I would recommend making a reservation ahead of time. Hope you enjoy your breakfast.
