A Slumberpod has been the best purchase we've made for travel. It is a pop-up blackout tent that can go over a pack-n-play or travel crib and provides a consistent sleep space no matter where you are. We've done probably 45 nights away from home in almost 3 years and the only time kiddo woke up in the middle of the night was the one night we didn't use the Slumberpod. Highly recommend.
