We have an 800a ADR for H&V on a non-EMH day.
Because my son only has interest in TSMM and no other rides, we decided to use our FP+ for another park in the afternoon.
I'm hoping we will finish breakfast around 850. Can we head there and get in line? Would you anticipate the SB line to be longer than 20 minutes, since many will use FP+ as a guarantee to ride?
I'd try to get out of breakfast by 8:45 as they open the park earlier than 9.

although we are planning on arriving for RD we are torn between heading to JTA an TSM. From what I've been reading here it's sounding like we need to head to TSM first. Has anybody had any luck with signing up with JTA later in the morning?
