Let's try sneaking in.

You knew for a fact there would be no way you could pay any kind of money and win a spot here. Besides, what if they found put you didn't actually have that money?

You walked away for now, looking for another spot you could enter in from. There had to be a way in aside from the front gate. As you searched, you finally came to a good spot to climb the wooden wall and get you inside. There wasn't any guards here, so this should be relatively easy to perform.

You climbed over the wall, landing down to the ground without hurting yourself. You were inside now, and you did have a few options. There might be a nice maid who might help you get inside. Though if you could find the noble's wife, or a beautiful daughter, you might just be able to have them speak with the noble. Nothing like a good fuck to make a solid connection with an important family.
