Festival grounds

A festival grounds is a lot assignment introduced in The Sims 3: Seasons. They typically replace the largest park lot in worlds released by EA, inserting many festival-related objects that change by season. They are controlled by a seasonal lot marker.

Seasonal lot marker
Festival grounds can be built with the use of a seasonal lot marker, which causes the lot to change throughout the year by setting certain objects to only appear during these times. It can be used on any lots, including residential lots. The marker does not affect features implemented by Build Mode like walls and roofs, however.

Seasonal effects
Each season the theme of the festival changes.

Spring - In Spring, the main theme of the festival is love. You will find objects like the kissing booth.

Summer - In Summer, the main theme is Summer fun. In this case there are objects like the face painting booth and the soccer goal.

Fall/Autumn - In the autumn, the theme of the festival is scary-themed. Here Sims can partake in activities like apple bobbing and visit the haunted house.

Winter - The theme in Winter is Winter fun. Here there is snowboarding and ice skating for Sims to do.
