Need help choosing a double stroller

Need help please. I have 2 kids and one in the way. one is 4yrs and the other one 2yr I’m due Oct. and Im trying to get a doble stroller that I can fit in a dr. office rooms or fit through a door, and its not heavy. I have a small car (Toyota corolla) , I need it to fit in my trunk. I bought a stroller similar as the Contours Options Elite ,but didn’t fit at dr office. And just to put it in the trunk I have to removed both sits and fold it. then I got Graco Ready2Grow Click Connect LX Double it fit lil more in my trunk. But now the problem is my 2 yr old doesn’t like to stay in his sit or standing he likes to run,so I have to have him w the sit belt. I don’t think the stroller I have would work w baby and my trouble maker ( I have lil problem, I get sweaty and in a bad mood when stroller doesn’t fit or have hard time folding it. like in a airports.And sometimes its just me and the kids) What stroller do you think is best. I saw videos of Kinderwagon Double Stroller and Phil & Teds Dot V3
