Stroller Questions...Double and umbrella?

[*CheshireCat*]

Hi Friends!

We are going to Disney in a couple weeks and would love any advice

Here are my questions:

*Should I rent a single stroller at the parks for either my 7 and 5 year in addition to bringing a collapsable double umbrella for my 3 year old and 11 mth old?

*Or bring our single umbrella in addition to the double umbrella? (we will be using the disney transportation)

Thanks so much!
