RoL - FP needed?

Heading to AK in late Nov with a 6:30p RoL showing. Am planning to book our FP for later in the day as we may choose to do a different park in the morning. Haven’t been able to get a dining package. Was planning to FP FoP, EE and KS, but would really like to see RoL. Is a FP necessary? Opinions much appreciated!

I’m not sure, but for the week we are going in October they recently added a showing to every night and a second showing on the day we will be there. So maybe standby would work? Also if you would like to book a dining package then just keep checking, that worked for us.
