We bought this luggage set for a recent Disney trip and it was wonderful. We have a family of 6 (2 adults and 4 kids, 7 and under) and I was able to get all of our stuff for a 5 day trip in this set with only an additional laptop bag and diaper bag. I was able to use the boarding bag at the park to store most of our necessities (sunscreen, sunglasses, snacks, etc.) and it's strap fit nicely over my Graco metrolite stroller handle. The luggage was very bright (aqua) at the airport for quick identification and it rolled like a dream in any direction. My 3, 5 and 7 year olds each took a bag and were able to roll them easily. The inside is nicely lined and they feel very durable, and the expandable feature is very nice. I like the sizes as even the large one would be hard to exceed airline weight limits if you are mostly packing clothes. The zippers also seem very durable and don't hang up anywhere. The handles are very solid and easy to extend and there are also cloth handles on the wheel end and the handle end for easy lifting. As my kids get a little larger and require more and larger clothes, more luggage will be necessary, so I will be on the lookout for a good deal on this set again.
