Since you HAVE to pick 3 FP+ what would you choose at Hollywood Studios for a 5-1/2 year old boy who is NOT into Frozen and won't ride most of the rides there--yet we'll be there for one evening and two mornings for character meals and to see Fantasmic (no package... just going to do standby). We'll do our best to get 1. TSMM and 2. Star Tours (hoping he won't be too afraid of it) but have no idea what to do for #3.
For our EPCOT day we're going to choose 1. Illuminations (just in case he isn't too tired to stay up), 2. Spaceship Earth and 3. Turtle Talk -- he is afraid of heights so no Soarin'.
At AK we'll likely choose: 1. Safari, 2. Lion King, 3. Nemo -- considered Kali River Rapids but not sure he'd go on it.
For MK we're going to try for the following (staying off site so I realize I may have to revise this):
Day 1: 1. Meet Ariel (my son's request), 2. Under the Sea Little Mermaid ride, 3. Festival of Fantasy parade
Day 2: 1. 7DMT (I realize this may be impossible), 2. Meet Tinkerbell (another request), 3. MSEP
Day 3: 1. Buzz Lightyear, 2. Tomorrowland Speedway, 3. Haunted Mansion
