This is a big decision, I know I went thru the same thing in January. I had my kids 2 1/2 & 14 months and my best friend with her 5 yr. old. I hate our umbrella type dbl stroller because it is really hard to manuver and our nice double stroller weighs a TON. The thought of lifting that huge thing onto the bus while carrying a 14 mo. old & helping a 2 1/2 yr. old - well I couldn't do it. Okay so I narrow it down to the pain in the butt dbl stroller with no storage or start deciding about single strollers. To make this long story end faster I decided to take our nice lightweight single stroller and my best friend would
rent a stroller for her 5 yr. old if needed.
This worked and it did not. There were moments I wished I had brought a TRIPLE stroller

which I do not own LOL. For the most part all 3 kids were in strollers at the parks. We rented a dbl. stroller for the 2 1/2 & 5 yr. olds while the 14 mo. old lounged in her own stroller
There is lots to consider:
Will you be using a car or relying on Disney buses?
How much walking do your children typically do?
How heavy is that stroller?
Etc.
