City Museum Excursion
At 7pm on the evening of Friday, August 3rd, we will be going on a group excursion to the City Museum, an exciting, hands-on, indoor/outdoor exploratory experience just a few blocks away from our hotel. Inside the museum, you’ll find caves, slides, walkways, and tunnels that carry you around the building and over the streets. We will be buying tickets at a group rate, so you must purchase your tickets here in advance. Tickets will be available until July 31st.
Please note that the City Museum requires anyone under the age of 18 to be accompanied by an adult at the time of admission.
