Get 7DMT for 3:30-4:30 and do that before CRT. Schedule one of the others for 5:30-6:30. I would suggest Pirates because I like doing Haunted Mansion after the party gets going. Almost any attraction (other than Peter Pan, 7DMT, and maybe Haunted Mansion) would seem like you are using a FP+ for it anyway due to short attraction lines during the party.
