I’m writing a detailed review for parents interested in Lil Ninjas: I took my 3 y/o son for a trial class on a Sunday. The building opens at 9am and class was scheduled to start at 9, which confused me a little. We arrived at 9:04 and class was already in full swing (no pun intended! so make sure you’re early/on time).
