I wanted to highly recommend the Doubletree Hotel in Philadelphia if you are ever looking for a great venue in hosting a conference. We have been using them for over 5 years, and couldn't be happier with the service that we have received. First, the location of the hotel is absolutely superb it is located near most of the major tourist and shopping sites of Philadelphia, so people can easily find fun dinners and activities to do within walking distance in the evenings. Secondly, it's located near a food court and a couple of lunch places, which our respondents have said they really appreciated having close by. As for the service within the hotel, everyone is always responsive, and always ready to fix any problems as soon as the crop up. The conference facilities are not located on the same floor as the main lobby, which for us, due to privacy reasons, is an advantage. Overall, we thought that everything from the setup of the tables and chairs, to making sure our technology works is handled professionally, and I trust the staff at the Doubletree implicitly. After having used them for several years now, I intend to continue to hold our annual conference in their facility, and highly recommend them to others.
