According to mainstream Christian Protestants, Is there a waiting place for the saints and the wicked where they are immediately received after death?

From the parable of the rich man and Lazarus, Jesus taught that both died but went to different destinations in the afterlife. Lazarus was comforted in Abraham's bossom which is paradise and the rich man received in Hades. These two destinations are temporary as the saints in paradise will later move to the new heaven and the new earth while those who wait in Hades will move from there to the lake of fire. I do believe that paradise is full of the saints from the old testament and the new testament such Moses, Elijah, Elisha and the rest. They also await the ultimate resurrection of every human being that has ever walked over the face of the earth on the last day. Are these destinations real or Jesus was symbolically speaking about what will happen after judgment where some people will be exalted to life and others sent to the lake of fire ?
