At one of the more enviable locations in San Diego, the 30-story Hilton Bayfront is right on the bay, directly across the street from PETCO Park. It's connected to the San Diego Convention Center and it has its own massive event space that's frequently used for spillover from conferences. The hotel's business-friendly environment includes an on-site UPS store and 1,190 large rooms with desks that are designed to get work done. It's not all meetings and conventions though, and the hotel has a great outdoor terrace with a saltwater pool and a waterslide facing the bay. With expensive food and added fees for Wi-Fi and parking, the Hilton can end up being an costly place to stay, which may deter those who aren't in town for business. Nearby alternatives include the Manchester Grand Hyatt San Diego, on the opposite end of the Convention Center, or the less spectacular Embassy Suites San Diego Bay, which has cheaper rates and free breakfast.
