We went with a group of 12 adults for a birthday on a Saturday evening. We did the zombie garage. None of us had been to an escape room activity before, and we all enjoyed the experience. The team was great and gave us all souvenir cups, and the birthday celebrant got a t-shirt and commemorative group photo for free.
I would recommend Ultimate Escape Challenge for people looking for something new to try. Next time I'd like to do one that involves more critical thinking and less adrenaline.
