Why has Sesame Street done multiple-episode stories?

[Stupendous Man]

tes the time when Maria and the cast went to Puerto Rico to visit her family was a week long episode. i rememeber seeing it.

Do you remember the storyline for those other episodes, besides #1316?

it's hard to rememeber everything or at least every single episode. 1 episode i rememeber was the last show where everyone was some public square and everyone along with others in the city or town gathered there for some event and a band was playing there and everyone was dacing, and so on.
