Not all members of the party.

So in the summer the word is that people are lining up as early as four or 5 AM to get those tickets that are sold on the same day. By 7 AM the line is reported to be 50 or 60 people long. So unless you like to spend most of your morning standing online I would look for other alternatives.

There are places selling tickets when they're sold out at a premium. You can also buy them as part of another tour and call and explain you're not going to go to the rest of the tour.
