You were by yourself as you only had one ticket with you, along with a ton of money. You go over to the ticket-vender, and give him your ticket, while in return he unlocked the velvet rope gate, keeping anyone who doesn't have a ticket out. Once the gate was open, you go on through, and take a look at what was inside.
Before noticing everything else, you see a sign that leads to different areas of the park. Looking at the sign all day was going to keep you distracted from everything else, but then you saw a basket full of maps that explain where to go in the park. You pick one up, and notice a sign that says 30 cents per map. You of course do what the sign says, and place your change in the bucket, where most people pay for the maps at. With the map you purchased, you followed where the map would take you.
