I said the same thing when I got snowy escape. I feel EA should have created festivals as a holiday players can make similar to Christmas and Easter. I think the festival lots should have been a special sort of lot designed for only festivals. We can decorate the lot with festive items and choose what festival we want to be there and on which day. Then players can change up how the festivals look, and instead of it being every weekend, we could set it to happen less often so missing it feels sad.
But instead the festivals are static and there is no way to shake things up.
