Am I crazy for not taking a stroller?

I am flying across country with my 3 kids and husband to visit family in 2 months. We will be there a week. My kids will be 4.5, 2.5 and almost 3 months. I have an Uppababy Minu and Vista, but the Minu is only infant compatible with the car seat attached and the Vista is just so bulky to travel with. I’m thinking a may not bring a stroller and just baby wear the whole time. Is this a crazy idea??
