Everyone is differnt. And I'm not askingfor opinions, but for for strollers that hold bigger chidren.
But my DD walks PLENTY! But I don't want o give up the stroller, for 1 the space issue of hold a bag, I love this feature with a stroller and I weil lbe sad whe nI have to go stroller free, but thats me. I have taken my other children (and this one) to Disney before, so I know how my family works. I went stroller free when I took my two older kids (now 18 and 21, and I had to carry my youngest at the end of each day because of blisters or too tired. She was 5 and 7 on those trips.
This stroller wil lbe used for trips with long days. We go to the parks when we wake up, sometimes not till noon, but we stay till closing with alot of walking, and I personally have found it easier to put my child in a stroller than to hear moaning and crying about feet. We can stay longer because she is refreshed from a rest.
Also I live in the country with NO sidewalks at ALL. I go for walks for exercise. My DD, 1 can't keep up with my exercise pace, and 2, I wouldn't let her walk on the road anyways. We are on side country roads, but still I don't want to have her walking by herself in case some wild driver comes by and she takes a wrong step.
Anotehr reason is for day trips,like the Zoo, which we went to yesterday. We also went with her 5 Year old friend. This friend told me last year that strollers were for babies when I pulled it out, then about 5 minutes later asked for a ride.

Yesterday this frined asked NONSTOP if she could ride in the stroller,...her feet hurt, her legs hurt...she was tired...Etc. Her mother had a stroller too, but her baby brother was in it.
In years past I wouldn't dream of a kid at the age of 5 being in one. But now that I have learned how much more enjoyable a trip can be when using one, I don't want to give it up just yeat. And you will see at Disney some kids as old as 10+ are jumping in strollers as the day wears on.
So I ask, don't judge, that wasn't the question I asked..whether I thought it was Ok to use one for a child that age...because I really don't care if you think it's not OK. My child is very active and can run circles around me everyday, but for my peice of mind this works when I need it. And it's not an everyday thing. But neither is Disney for us.
