Asilomar is one of the best conference centers I have seen -- much nicer than typical convention centers or hotels. You can stay on the grounds for convenience and the meals provided are decent and filling.
One of the attractions to Asilomar is the way the buildings are situated. To get from room to room, you stroll through woodsy walkways and you can see the ocean across the road. During lunch, I like to sit on the beach and watch the waves roll in -- its very therapeutic!
If you are looking for a place for your business to have a conference that employees will appreciate and enjoy, I highly recommend looking into Asilomar's facilities.
