Wouldn't advise brining anyone along and making a big fuss out of it. You don't need any additional pressure. Instructor just hopped out and said "Ok, the dead weight is out of the AC, be back in 40 minutes"...only nerves were taxiing and holding short, checking the "lights, camera and action"...once you get rolling the training kicks in.
Enjoy it, and like a few people have said already, don't be afraid to go around or decline an ATC request if unable, after all you're in charge now!
Good luck.
