Hi ILs, I am planning for a trip to visit few places in east coast. We are planning to visit Newyork, PA, Niagara. My kid is three and half years old. I havent used stroller for him till now. As this gonna be a long trip and I wanna buy a new stroller for him. I would like to know,how do you all manage to carry stroller when u travel around.(from one state to another). Do you buy one when u reach the destination place? Need some tips or ideas.. Also, pls suggest the must see places in NY,NJ,PA and around. We have 3 weeks of vacation and wanna spend it properly to visit most of the places there. Any suggestions pls.
