Hobby lot
A hobby lot is a secret lot in The Sims 2: FreeTime expansion that specializes in one of the hobbies. Increasing a Sim's enthusiasm in the hobby to level 5 will reward them with access to a special secret lot. Instructors are NPCs that can be found on each of the secret lots and instruct Sims in the lot's designated hobby. Often, the Instructor is the Sim who gives the pass to Sims.
While Sims cannot gain skill points and talent badges on normal community lots, they can gain them on hobby lots. Therefore, they make more effective gyms, libraries, studios, etc. than normal community lots.
Sims can also take other Sims with them to the hobby secret lots even if the invited Sim doesn't have access to the secret lot. Some hobby lots also contain items only normally available as career rewards. Hobby lots are also places where Dormies, Downtownies, and random selectable NPCs can visit outside their native areas.
The pass will show up in the Sim's memories. Townies may be created with level 5 enthusiasm in a hobby. If they are made playable, they will have access to that hobby's secret lot, but may not get the pass in their memories.
