How would you handle AA here on the flop on button?

[Haplo]

I had a bad feeling I was beat when dude went all-in (no info on limper). It was 14 more to call and about 36 in pot. Felt committed.

Would a pre-flop raise to say 5xbb have been better from button given there was already one limper? What do some of you typically do with that hand in that position?

Comment appreciated. Thanks.
