Suggest only going with Play if nobody within Poland will be calling you. The rates are crazy, from Orange/Plus/T-Mobile to Play. I use Orange. It's probably the weakest network of the big three, but the rates are very low, and it works every time I come to Poland (like right now). If it's only calling you're looking for, then Orange is great. If it's a combination of data and voice I still recommend Orange, especially in the big cities. If it's just data in the big cities, then go with Play.
