It's easy to put together and take a part. The stickers were hard to place but that's not a big deal to me. My son, now almost 10 months, hates being confined. The play pen was very sturdy but he wouldn't stay in there without crying. I ended up buying another one and using sections of the pen to block off areas of the house. It's not as sturdy when not put together in a closed shape, but it works for us.
Some basic models may be easier to cart around because they don't have any extra parts. You can also look for bags that leave the play yard's wheels free, so the whole thing can be rolled once it's packed up. If you plan on taking frequent trips (especially by air), you might want to consider a heavy-duty bag that you can buy separately, such as the Rover Gear Easton Travel Yard Bag (about $34).
If your play yard is going to function mostly as a play space for your baby, or you're on a tight budget, you can probably go with a basic model and skip the accessories such as mobiles and bassinet insert. A pair of lockable wheels or swivel casters on one end of the yard will make it easier to move from room to room. If you'll use it for travel, you'll want a play yard that's lightweight, folds quickly and compactly, and has a carrying case. You may even want to be able to roll the packed unit. A carrying bag that allows the play yard's wheels to roll when it's packed is ideal.
This thing is great. I have it set up as a wall spliting my living room in half basically. The panels are sturdy so hold up great when my daughter pulls herself up standing against them. As i have it set up as a wall i did anchor it to the room walls byattaching some Velcro to the room wall with a screw at either end then wrapping the Velcro around a piece of each end section. This has allowed me to create a baby safe area with all her toys and then an adult safe area with no toys to trip over, and itlet meget away with not baby proofing the entertainment center.
