A single stroller rental currently costs $15 per day, and a double costs $31 per day. Buying multi-day/length of stay rental saves $2 per day for a single and $4 per day for a double. A $100 deposit is required for strollers rented at Downtown Disney.
Show the receipt to the stroller rental at the next park and you will not be charged any additional price for this new stroller. You only pay once for stroller rental each day even if you go to all of the parks. Just keep that receipt handy. Rented Disney strollers cannot be removed from the parks.
