There are only two ways I could see you not counting Aladdin as a trilogy.
1. You count the TV series as a fourth entry, in which case you would have to count the extended universe/spinoffs for everything ever, leaving very few actual trilogies.
2. You're of the mindset that Disney sequels don't exist, in which case I'd usually agree with you but the Aladdin ones were actually pretty decent.
