I am getting married next year in the greater Philadelphia area during Pope Francis's visit to Philadelphia. Because of this, most hotels are unable to accommodate block reservations, though they will have rooms for individual reservation. We therefore are trying to get our Save the Dates out as soon as possible so that guests are aware. What would be the best wording to include to advise our out of town guests to reserve their own rooms sooner rather than later? I was going to include something like "His Holiness Pope Francis will be in Philadelphia for the 2015 World Meeting of Families during this week. Please be mindful of the high demand for lodging this weekend and plan accordingly." along with some nearby hotels. Thanks for your advice in advance!
