Yes! Definitely a game changer. We just went to Hawaii and I rented Different things on each island (was there for an extended period of time for work and had to bring the baby with me because he refuses a bottle). I used babyquip.com. It was super easy to use, rent, and the delivery was prompt. The equipment was very well maintained and super clean. The best part was return, they made it so easy as they tell you when they will pick up and where to leave the items. Highly recommend. Items I rented: pack and play, bouncer, stroller with skateboard attachment (I have a three years old as well). With so much stuff including car seats to travel with it was nice to rent a couple essentials and not have to deal with the giant stroller for two at the airport.
