We have stayed in the FFI several times. Actually everytime i have been in the past 15 years.
Pro:
It is walking distance
It has quiet (brick wall) rooms
I could use the Marriott point so i stayed for free
The restaurant out front was great and Mimi's is close
DL Fireworks can been seen from the walkway
McDonalds is basically in the parking lot
Not directly in front of parks so the only people there..belong there
SoSo:
Pool in parking lot, essentially, but you don't notice when you in the water
No real services, little gift shop, Pizza Hut with coffee is only on-site food.
We are staying at the Stovall this trip as it was $900 vs $1200 for the same package (5 nights/3for5 park hooper/premium charact meal and basic DL Travel package) via Costco.
AAA was very close on price but no Premium Character Meal and included something different.
