Side by side double stroller vs. inline double stroller. which is better?

I have a 2 year old and a 5 month old. I've been wanting to get a double stroller but dont know if I should go with inline or side by side. My only concern on the side by side stroller is, How do you get by through regular doors since this stroller is really wide. Is there a way to get through regular sized doors. thanks. I appreciate any feedback...
