The address I am getting is 1101 Arch St. in Philly. I would like to be able to walk to the center, but it is not 100% necessary. I could grab a cab if I had to. But it will be in June, so a long walk (half hour or so) wouldn't kill me. If it's possible to get within a half hour's walk, that would be ideal. They gave us several hotel possibilities to go through the conference organization to secure a reservation. They are the Comfort Inn, Cortyard by Marriott, Crowne Plaza, Double Tree, Embassy Suites, Four Seasons, Hampton Inn, Hilton Garden Inn, Holiday Inn Express, Holiday Inn Historic District, Inn at the Union League, Latham Hotel, Loews Hotel, Park Hyatt, Marriott, Radizon-Plaza Warwick, Residence Inn, Ritz-Carlton, Sheraton Society Hill, Sofitel, Westin, and Wyndham Franklin Plaza. All of these are supposedly within a half hour walk. I would prefer one of the nicer ones (what appears to be a 3 or 4 star on Priceline's scale).
