Most manufacturers make play yards that are designed to move. Many roll on wheels and fold easily and compactly into their own totes, which resemble short golf bags (although less rugged), making them ideal for trips or jaunts to Grandma's. As we've said, basic play yards tend to be smaller (about 28 inches wide) and lighter (about 20 pounds) because they're not loaded with extras. If you can find a model that fits into its travel bag with its wheels exposed, it can make moving through a busy place such as an airport easier. The Chicco Lullaby LX mentioned above does that.
I absolutely love this! It's great for uses outdoors with a baby boy who likes to eat grass and dirt! Keeps him in one area and off of the grass with a blanket placed under it! :) it's also AWESOME for indoors when you're trying to clean, take a quick shower or keep the baby away from the things they aren't supposed to have! My son loves it because he can stand up while holding the panels and walk all around it! Just a heads up for new buyers and possibly old THE PANELS DO CLICK TOGETHER. I did not know they did but just pull up on them and they snap right together! I found this out on accident :) it was the only issue I had with it and well... it's no longer an issue!
It's helped us out tremendously. It provides a way for us to cordon off a safe space for our son while allowing him an area to freely move. The fact that it breaks apart and can be arranged in various patterns allowed us to expand that space with some creative use of furniture. Sadly though like all young raptors, he's testing the gates, looking for weaknesses that he'll eventually use to escape and terrorize the local populace of cats.
