Double Stroller?

I am undecided on whether I'll be getting one in the first place, but I'd appreciate advice/opinions if you have any. My babies will be 24-25 months apart. My first absolutely despised the stroller so I basically wore her everywhere for the first 3-4 months. Will I even need one? Is it worth the investment? Will my daughter be walking enough/have enough stamina? She's running and started walking 2 weeks before her 1st birthday.
