Double stroller vs two strollers?

MrsS

We have a 2 & 4 year old and might be going to Disney later this year. We have a Maclaren stroller that worked well when we were there last, but we definitely needed a second stroller. I’m just wondering if I should buy another single stroller or invest in a double? It was nice that the Maclaren folded up small especially when trying to get on the tram at Disney.
