Double jogger stroller

I have a 15 month old and am currently pregnant. I love my bob jogger stroller but will need to get a double stroller. Take it everywhere( I.e. hiking paths and zoo)

I thought about a bob double but I am not sure if the side by side seats would make it difficult to get through doorways or places where I may need to go through a line like the zoo?

Any product recommendations? Or thoughts on the side by side versus the front and back style strollers?
