In the preview above, the 'Pajama Friends' cast members Song Ji Hyo, Jang Yoon Joo, Red Velvet's Joy, and Cosmic Girls's Cheng Xiao arrive at their luxurious hotel. At first, Jang Yoon Joo worries that they'll be lying around in bed the entire time for their 'Hocance' (hotel + vacance), but soon, the women find out just how much there is to do at a luxury hotel. 

At the end of episode 1, it seems a surprise guest also pays a visit to the cast members' hotel suite?

Only one week away until the premiere of 'Pajama Friends' on September 15 at 11 PM KST!
