When making a sightseeing schedule find out when museums offer free admission

Many large museums offer free or "pay-as-you-wish" admission one or two days per week, often for just part of the day (the first couple of hours in the morning, or a few hours late in the evening). Thursday and Friday evenings are common for this practice, but exact days can vary greatly—you might be able to plan your museum visits to get into several places free. Keep in mind, however, that most museums are nonprofit. If you are in a financial position to make a donation, it’s always appreciated.
