Touring with DD when she was 15-months-old was the easiest out of all of our trips. At that age she was content to toddle around, take in the sights and sounds, and loved the characters and attractions. I made sure she stayed hydrated and had a little fan that clipped onto the side of her stroller. I always kept a small snack (grapes usually) on hand as well as a favorite (small) toy to entertain her if we were in long queue. Naps were critical but figure out what works best for you. I tried going back to our resort in the afternoon but DD was so excited and overwhelmed that instead of sleeping she kept pointing to the door and yelling "Ma! I go!". After two days of that I threw in the towel and she napped happily in her stroller for 1.5-2 hours each afternoon while we remained in the park. I simply settled on a bench or roamed the shops until she woke up.
