LOL!
Sometimes I get three cakes from three different families. Not only they feel awkward I get a sinking feeling, what could I do with so much cake???
And poor crystalwear just gets passed along to another house. It may not even match the house furniture. Best thing is a good smile and casual activity at my house. Play cards, shoot pool, jump in backyard pool, do BBQ, play carrom, watch game, do prayer together whatever. Just don’t bring a cake!! 
Waisey, it may be that they are really busy. Still calling ahead is a good idea.
