Definitely bring your own stroller. If you are staying on site it can be a hike from your hotel room to the bus depot. If you will be taking Disney transportation then I recommend having 2 strollers that are very light weight and easy to collapse for getting on and off the busse, boats and monorail. I also recommend tying bright red ribbon on your stroller so it is easy to spot. The strollers do get moved by cast members (to be closer to the exits) but I never had a problem finding my stroller with the red ribbon:). Have fun!!!
