I agree, definitely be honest. I can't image that it is THE deciding factor in whether or not you get accepted. Honestly, it didn't hurt me.
I was asked during my interviews about other schools I applied to and was honest about it. Each school has its own unique qualities from the others you applied to. Just be sure to explain and highlight why you chose their school.
It is a huge investment of money to apply so decide accordingly and thoughtfully.
Good luck with apps!
