On July 6th, there is a Tailgate Like a Champion event that involves a Phillies Tent Party at Citizens Bank Park before the Phillies vs. Cincinatti Reds game at 7:00. If you hit that soiree and stay at the Philadelphia Doubletree with the Philly Overnight Hotel Package, you could win an "Ultimate Game Experience," which includes "a personalized authentic Phillies jersey, a private tour of Citizen’s Bank Park the next day, and getting a view of lifetime (at least for half an inning) in the Phillies broadcast booth during the Cincinnati Reds game on July 6th." Free parking is included in the Philly Overnight package, too.
The Doubletree Philly had some rooms recently renovated, and TripAdvisor reviewers have been saying generally positive things about the location and their stays though the impression that we get is that it's pretty much your standard big-box-hotel in a big city.
