I would skip AK. Our family loves DHS and would never skip it. My 4 year old son LOVES Disney Pixar movies and he LOVES meeting the characters here. TSMM is a great ride not to be missed also. We try to spend 2 days here if possible.
Our last 8 day trip, we did not do AK. We will next time, but for us slipping is not a prob. Our 4 year old can't ride the biggies there except for the Safari. The one time we rode it, we sawhardly any animals but a few. He saw more at our local zoo and he just was not excited about it.
Our next trip we will go to AK but if we had to skip park, AK will be it.
