I decided to not ruin my first day at Disney World (on this trip) by rushing through AK rope drop on a morning when there will be tons of people attempting the same since the 5k runDisney starts and arrives in the AK parking lot that day... Plus, I do not want to get hurt the day before running the WnD challenge.
So I moved my other AK fastpasses to the afternoon and will wait for FoP if the line is not crazy. It will give me time to rest in the shade. Also, I am sure my first impression on Avatar will be more positive.
If that doesn't work and I think it is worth it, I will attempt again at park closure the next day, this way I'll see Pandora at night.
