yellowstone park-i want to camp in one place, where should I

I'm glad I posted this question on here guys. This has been a real help. We are definitely going to take our dog along. Now I have one more question. I wasnt going to post this, but what the heck.... I am planning on asking my girlfriend if 4 years to marry me while on this trip. Any suggestions on a good place to pop the question? We want to see as much as we can in our limited time there, so we won't be going on any long hikes....but a mile or so wouldn't hurt me if it ends up being a great spot to surprise her.
