Pad thai is not a dish I recommend making for a party. It's hard to make a large amount of pad thai using a home stove—you will need to make multiple batches. Also, the noodles don't sit well and they are best when eaten fresh off the wok. If they sit for too long the noodles will start to clump up together. It IS possible to do it for a not-too-big party, but I would cook multiple small batches, and plan it so that people will eat them shortly after they're done.
