iam enlish 粉丝 who will be visiting scranton, and i would like to know if there are tours etc of scranton, to see filming locations, also can anyone recommend any cheap hotels in the area thanks in advance

Why they may not film in Scranton, many of the places they talk about are actually there, like Cooper's, Poor Richards, the Coal mining museum, Lake Scranton, etc. Here is a link to everything they have mentioned in seasons 1-3 and a map of
Scranton:
