On February 21, Fantagio iTeen posted photos of the girls spending quality time in Los Angeles' Disneyland on their official Facebook page.

"Hey everyone. It's the Do-Deng sisters.  We are currently having so much fun here in the States. Please wait just a little while as we will return with much experience. See you in Korea."

In the photos, Choi Yoo Jung can be seen clinging onto Goofy while Kim Do Yeon makes a chic pose.

As previously reported, the two girls flew to LA on February 14 following the disbandment of IOI. They flew to the U.S. to relax (Disneyland) and also a learning experience as they will meet with well-known American music producers such as Lauren Giraldo, Francis, Pitbull, B.O.B, Mac Miller, Jose Iopez, and more, as well as vocal trainers, dance trainers, and more.
