Christine, since you only have 5 days to do your research I would advise you to hire someone to help with the research. I went to Poland last May and hired Zenon from Polishorigins.com to help me. We were there for five days and managed to find records which the LDS Church did not have plus find family in some very small towns. We did research in Zamosc, Lublin and contacted the parishes from the villages that my ancestors came from. I do not speak any Polish but many people in the cities do speak English. It was a marvelous experience and Poland is a beautiful country.
