We're planning a trip to bring my 2.5 year old son to visit the National Museum of Natural History and the National Zoo in the US.
Our hotel is right by the metrorail, and our plan is to take it in to the museums, returning for nap time and the evening.
We're traveling mid-week (Thursday and Friday), and want to get in to the museum/zoo as early as possible.
Is it permitted to bring a stroller? Will this be practical if we run into heavy commuter traffic, or should we schedule to avoid the worst of the rush (and if so, what is the best time in the morning to travel?)?
