We did both shows last week. On 1/3. Pretty busy day
We did start with a FP but in the end didn't use either due to late arriving
And late arriving worked to our favor
We got to LK about 5 min before showtime. They put us in seating usually reserved for wheelchair areas (it wasn't needed) so we got right up front and didn't wait any
Then we headed over Nemo and got there about 5 min before that show and also didn't need our FP. Walked right in and sat in about the 5th row also very good seats.
