How many people can fit in and around the park memorial?

I would agree with Jedi Star. I was there in November. Open air with plenty of room and the rangers are very knowledgeable.

Oh the park is open air and you can fit plenty. If you are party of 20, you can fit, but do social distance with others. For the moment everything is close , so no tour at all, but the memorial is outside in the open and is self guided. There are 3 rangers at each area and he or she can answer questions and they can also give you information of MLK from childhood to adult.
