I  (29F) am throwing a party, and sent out the invites some time ago. In the RSVP portion of the invite, I asked for a text or call by a certain date. The due date for responses has come and gone. I have had a handful of people who have responded. I am pretty certain that other people (early 20's M+F) who were invited are just going to 'show up' at the party. I will be prepared food wise, but the favors for the party will be in short supply. By this I mean, I only want to give the party favors to people who were courteous to RSVP. 

I am wondering how to handle this situation. I do not want to call people to see if they intend on coming, as I am putting this party together alone, and have a full plate. I also don't want to feel like I am pressuring anyone to attend. Is there a tactful way to only offer party favors to those who have let me know that they will be in attendance? I will make sure that there is enough food for everyone, but since the favors are labor intensive I'd rather not make a bunch of extras 'just in case'. Is there a way to gracefully handle 'party crashers'?

I have a suspicion that people who didn't respond to my invite will show at my party
