Not only did Disney increase the cost of renting strollers, they changed the design. With the new strollers, Disney reduced the size and weight limits of both the single and double strollers - single down to 35 pounds and double down to 65 pounds. In other words, our two-year-old daughter will not fit in a single stroller. They currently only have the new strollers in two of the four parks, so we hope this is a test and in our opinion, these strollers fail the test.
Not only are the weight limits too low, the strollers are more narrow than the previous version, forcing your children to be very uncomfortable and creating a constant fight to keep them in the stroller. Also, as you'll see in the photo, below, the wheels angle outward, causing a problem with the rails on Main Street, as well as a catch/trip-hazard at all the poles that create the lines at Disney World.
Hopefully, Disney receives lots of feedback on these and makes the right decision.
