We went to WDW last year and got a stroller for DD everytime we were in a park for more than a couple of hours. This was a month after she turned 4. She had not been in a stroller for at least 8 months before that and has not been in one since. Next year we are going a month after she turns 6. I know that she won't NEED a stroller but it was a very convenient way to carry the backpack, etc. So my question is, do we rent a stroller or severly downsize the bag? Last year we carried cameras, water bottles, wipes, underwear changes for both kids, ziploc bags, sunscreen, anything we bought, etc...
