My son never took a bottle or formula. But, he drank water or juice from a sippy cup. My daughter also won't take formula from a bottle, just breast milk. However, she'll take formula from a sippy cup. They have the soft spout sippy cups. Give it a try & good luck to you.
Just an added suggestion: When we went to Disney, we put a sticker on the back of our son everyday that had our cell phone # on it. Just in case he got lost in the crowd. Have fun.
