We have an 8am adr for Breakfastosaurus in AK then have a 5pm adr for HDDR. Will that give us enough time at AK? What time should we leave AK in order to arrive at FW in time for our 5pm dinner/show? Is there a bus from AK to FW or is there a better way to get from one to the other? In case it matters, this will be in October when park hours are possibly shorter. Thanks for any insight! 

Do you have a rental car or are you just using the bus system at Disney? Keep in mind that you get a lot of food at HDDR and it is a great show. So with the big breakfast you will have, you should be good for the day. What resort are you staying at? If you leave AK I say at 3:00 you should be ok. That would give you time to get to your resort and change if needed. You could then park at WL and take the boat to FW. While waiting to get into HDDR, enjoy the pet farm at FL.
