And I MUCH prefer one larger stroller to two smaller strollers. With two strollers no one ever has a free hand, it's harder to split up, navigating through crowds, imo, is harder with two than one, I don't trust the stroller connectors, more to keep track of. Of course, whenever I hear (read) of someone complaining about double strollers or travel systems, it's always a Graco. I don't have Gracos. I have an evenflo travel system, and evenflo tandem, a schwinn double jogger, and about to buy a peg pergo side by side. I have a baby trend lx sit n stand and a baby trend single jogger also, but I HATE those!!
Anyhow, my big question I like to ask is "do you really want to spend money on another stroller?" Will you use it regularly or is it just for this trip? Does your regular stroller bother you much during regular use? If not, it will be fine for Disney. What do you have to give up (souveners, character dining, hotel upgrade, etc) to get the stroller?
Only YOU can decide what will work best. Everyone has different tolerance levels--with 3 ages 4 and under, active lives, & living in the suburbs, I use a stroller regularly and it just doesn't bother me. A city dweller who rarely uses a stroller will feel differently. Just yet another interpretation of life.
