Is that too many for same day fastpass grabs after we do our initial 3? Should I split the group up when booking or is 5 still an ok number to manage?
You should be fine. If you don’t see anything for 5, split after that and try to get overlapping times.
I think you should be fine. We were able to get 5 SDFPs for FOP a couple of times, TT, SDD, TSM in July. Never had to split the group up.
